New in ChemDraw Professional & Prime 20 Version 20 Version 19 Version 18 Version 17 Version 16 Version 15.1 Version 15 What's New in ChemDraw Professional 20 3D Clean-up and Structure Perspective A new 3D clean-up function will generate 3D confirmations of structures from 2D representations, to generate realistic 3D renderings in just a few clicks. Atom/Bond highlighting Complementary to the version 19.0 Ring Fill coloring, atoms, labels and bonds can highlighted with a specific color to facilitate communication and audience focus. What's New in ChemDraw Professional & Prime 20 New Atom Hotkeys and new Molecule Hotkey A new Molecule hotkey "Enter" is available to switch from a selected molecule to hotspot molecule editing. "k" now creates a sulfone group, "Shift+k" on primary carbon gives a tert-butyl group with 90° angles and on secondary carbons a wedged/hashed-wedged gem-dimethyl group. "Shift+o" creates a "OMe" group, and "Shift+e" a "CO2Me". Upon 1st launch of ChemDraw 20.0, a comprehensive hotkey cheat sheet will be presented to the user. What's New in ChemDraw Professional 19 New coloring options As one of the market-leading tools for the communication of Chemistry, ChemDraw Professional 19 now offers the unique possibility to add color inside any carbon cycle, thus enabling clearer communication of ideas and concepts by directing the focus of a reader or an audience to a given part of a chemical structure. Large chemical library enumeration ChemDraw Professional 19 removes the previously existing upper limit to the number of structures generated from a generic structure enumeration. It is now possible to enumerate directly to an SD File, without a limit to the number of molecules contained therein. New SciFindern Interface SciFindern users are now able to initiate a search in the latest version of SciFindern directly from the canvas in ChemDraw. A proxy option is available for organizations that have their own instance of SciFindern. What's New in ChemDraw Professional & Prime 19 Smart Polymer Brackets New brackets are now available in ChemDraw Professional and Prime 19 to better serve polymer chemists, allowing them to define Average Molecular Weight values for a chemical structure between brackets for easier stoichiometry calculations. More Hotkeys One of the most user-favorited feature and a major reason to upgrade from older versions of ChemDraw keeps on getting better in Version 19. Commonly used protecting or functional groups in all branches of Chemistry like "Fmoc", "Boc", "Cbz", "MgBr", "N3" or "COOH" and "NO2" are now conveniently available in one single key press. New in ChemDraw Professional 18 ChemDraw/Elsevier® Reaxys® With ChemDraw Professional 18, it is now possible to draw a molecule or a reaction in ChemDraw, and initiate a structure search into Reaxys. You can also choose to use ChemDraw JS as a drawing editor when you use the online Reaxys website. The access to Reaxys is chargeable and must be obtained separately. Facilitated chemical structure pasting ChemDraw Professional 18 now supports a simplifed, more direct pasting of CDXML and other text formats like SMILES, Mol, InChi, and HELM as a structure using the "Edit >Paste" (Ctrl+V) menu option, with plain text in the clipboard. You can also copy/paste to and from ChemDraw JS, ChemDraw and MS Office embedded ChemDraw documents without loss of chemical information (requires browser-specific clipboard extension, Windows only) HELM Editor Following the HELM standard, developed by the Pistoia Alliance for the rapid transfer of biomolecules, a custom editor for creating, editing and sharing complex biomolecules has been added. Importing biomolecules using the HELM notation format, editing the biomolecules, creating and using your own custom monomers and exporting out via the HELM format is now easy. New in ChemDraw Professional 17 Hotkeys Enhancements The hotkeys and reaction shortcut enhancements will improve your user experience with ChemDraw 17 by cutting down drastically the amount of time needed to draw complex molecules and reactions to a sequence of key strokes. It is also now possible to switch between the different tools without relying on timeconsuming back and forth movements with the mouse. With the new hotkey enhancements you will spend far less time on drawing your reactions and much more time focusing on your research! Dramatically reduce the time needed to draw your molecules with smartly designed hotkeys. Draw your molecules and reactions without having to rely on back and forth gestures with the mouse. The new hotspot visualization system allows you to see the active atom or bond, which can be moved with keyboard arrows. Switch between tools by simply pressing on designated keyboard keys. New reaction shortcut allows you to draw a sequence of reactions in no time, extending automatically the length and width of the page as you draw. Support for Hierarchical Editing Language for Macromolecules (HELM) Create novel, complex biopolymers with the new HELM editor. Today's chemists are eager to turn customized biopolymeric sequences into novel compounds – and ChemDraw 17 gives you the tools and the language to do it. ChemDraw now features support HELM notation, the Pistoia Alliance's emerging global standard for representing and sharing complex molecular types ranging from natural or unnatural peptide or nucleic acid sequences. Import, draw, edit and export complex biomolecular structures, containing natural or custom and unnatural monomers by selecting from a comprehensive list of peptides, nucleic acids or chemical protecting groups or via HELM strings. Paste a HELM text string into a fully chemically-interpreted HELM sequence that can be expanded and contracted as per your display needs. Easily search for specific monomers using the HELM toolbar filtering capabilities, through type-ahead filtering and, of course, structure search. Define and store your own custom monomers to be used into your HELM sequences. Neu in ChemDraw Professional & Prime 17 Advanced Document Tagging Easily add custom-defined metadata fields to your ChemDraw 17 documents to allow you for an easier retrieval of information. High resolution monitor support for Microsoft® Windows® ChemDraw 17 now supports high resolution (4K) monitor display for Windows®.
