P2p to oxime
WebOxime. In organic chemistry, an oxime is a organic compound belonging to the imines, with the general formula RR’C=N−OH, where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds. WebOximes are the chemical composites that belong to the class of imines, having the general formula of R1R2C = N OH. Oximes can also be made by the action of hydrogen-giving reagents upon certain nitro composites or by the isomerization of nitroso composites. The oximes attained from aldehydes (aldoximes) can be dehydrated to form nitriles.

WebThe reduction of oximes or oxime ethers and esters to primary amines is a useful synthetic transformation that is used as a substitute for direct reductive amination to convert ketones or aldehydes to primary amines. The reaction involves reduction of C N bond and reductive cleavage of N–O bond. WebMay 22, 2024 · The oxime group contains two H-bond acceptors (nitrogen and oxygen atoms) and one H-bond donor (OH group), versus only one H-bond acceptor present in carbonyl groups. This feature, together with the high polarity of oxime groups, may lead to a significantly different mode of interaction with receptor binding sites compared to …
