List of computer-assisted organic synthesis software

Computer software for computer-assisted organic synthesis (CAOS) are used in organic chemistry in tandem with computational chemistry to help facilitate the tasks of designing, predicting, and producing chemical reactions. CAOS aims to identify a series of chemical reactions which, from a starting compound, can produce a desired molecule. CAOS algorithms typically use two databases: a first one of known chemical reactions and a second one of known starting materials (i.e., typically molecules available commercially). Desirable synthetic plans cost less, have high yield, and avoid using hazardous reactions and intermediates. Typically cast as a planning problem, significant progress has been made in CAOS.

Examples of CAOS applications include:

• Spaya - Retrosynthesis planning tool freely accessible provided by Iktos
• IBM Rxn - [1]
• AiZynthFinder - A freely accessible open source retrosynthetic planning tool developed as a collaboration between AstraZeneca and the University of Bern. AiZynthFinder predicts synthetic routes to a given target compound, and can be retrained on a users own dataset whether from public or proprietary sources.

• Manifold - Compound searching and retrosynthesis planning tool freely accessible to academic users, developed by PostEra
• WODCA – no trial version; proprietary software
• Organic Synthesis Exploration Tool (OSET) – open-source software, abandoned
• CHIRON – no trial version; proprietary software
• SynGen – demo version; proprietary software; a unique program for automatic organic synthesis generation; focuses on generating the shortest, lowest cost synthetic routes for a given target organic compound, and is thus a useful tool for synthesis planning
• LHASA – demo available but not linked (?); proprietary software
• SYLVIA – demo version; proprietary software; rapidly evaluates the ease of synthesis of organic compounds; can prioritize thousands of structures (e.g., generated by de novo design experiments or retrieved from large virtual compound libraries) according to their synthetic complexity
• ChemPlanner (formerly ARChem – Route Designer) - is an expert system to help chemists design viable synthetic routes for their target molecules; the knowledge base of reaction rules is algorithmically derived from reaction databases, and commercially available starting materials are used as termination points for the retrosynthetic search
• ICSYNTH – demo available; proprietary software; A computer aided synthesis design tool that enables chemists to generate synthetic pathways for a target molecule, and a multistep interactive synthesis tree; at its core is an algorithmic chemical knowledge base of transform libraries that are automatically generated from reaction databases.
• Chematica (Now known as Synthia)
• ASKCOS – Open-source suite of synthesis planning and computational chemistry tools.
