Reaction rule retrosynthesis
WebJun 1, 2024 · A two-step retrosynthesis approach using deep highway networks (DHN) has been proposed [ 16] to avoid the vanishing gradient problem, where the likely group of reactions was predicted in the first step followed by identification of the required transformation rules using a more specifically trained DHN on the reaction group. WebTypically cast as a planning problem, significant progress has been made in CAOS. Some examples of CAOS packages are: Spaya - Retrosynthesis planning tool freely accessible provided by Iktos.

An amino acid has two functional groups –N H2 and –COOH. When two amino acids (A and B) react under conditions for the peptide bond condensation reaction, a mixture of 4 dipeptides (at least) could be formed as shown below.
WebRetrosynthetic analysis is a technique for solving problems in the planning of organic syntheses. This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents. Each precursor material is examined using the same method.
