Advances in the Use of Synthons in Organic Chemistry

In retrosynthetic analysis, a synthon is a hypothetical unit within a target molecule that represents a potential starting reagent in the retroactive synthesis of that target molecule. The term was coined in 1967 by E. J. Corey. He noted in 1988 that the "word synthon has now come to be used to mean synthetic … See more In planning the synthesis of phenylacetic acid, two synthons are identified: a nucleophilic "COOH " group, and an electrophilic "PhCH2 " group. Of course, both synthons do not exist per se; synthetic … See more Many retrosynthetic disconnections important for organic synthesis planning use carbocationic synthons. Carbon-carbon bonds, for example, exist ubiquitously in organic molecules, and are usually disconnected during a retrosynthetic analysis to … See more This term is also used in the field of gene synthesis—for example "40-base synthetic oligonucleotides are built into 500- to 800-bp synthons".
