Newly developed NeoGRRM has produced new results for BCNOS below.

　

Synthon Analysis Finding fragmentation processes of a target product tells us its synthetic routes.

Fragments indicate the reverse synthesis Ideal reaction without byproducts can be realized.

Discovery of A→B+C indicates the reverse B+C→A. Namely, fragmentation (Dissociation) shows the reverse synthetic route. ADD-following (ADDf) algorithm equipped in the GRRM program makes it possible to discover valuable synthetic routes by exploring dissociation channels.
Such a synthetic route yields no byproducts at all, and it is an ideal reaction saving resources. GRRM program enables us to explore valuable reaction routes automatically with neither excellent knowledge, experience, nor inspiration.

Example of Synthon Analysis: .......... New synthetic routes of Glycine, an amino acid molecule

Let us consider Glycine H₂NCH₂COOH as a target compound. At first as shown in the above figure, explore fragmentation (dissociation) channels starting from the target compound of Glycine. As can be seen in the above figure, the automated exploration yields various reaction channels generating ammonia NH₃, carbon dioxide CO₂, hydrogen molecule H₂, and carbon monoxide CO. Tracing up these fragmentation prodesses backward lead to synthetic routes of Glycine with no byproducts. Such analyses enable us to explore valuable synthetic routes.
Further synthon analyses of acetolactone H₂C(O)C=O generated together with NH₃ gave reaction routes producing (CO₂, CH₂) and (CO, HCHO). Consequently, (Step1a) CO₂+CH₂ or (Step1b) CO+HCHO may produce acetolactone H₂C(O)C=O, and the further reaction with NH₃ (Step2) generates Gycine with no byproduct.
