WebA few years ago, Bogn et al.2 reported the synthesis of 3-hydroxyflavanone oxime and 3-hydroxy-5,7,3',4'-tetramethoxyflavanone oxime. Considering the stereo- chemical … 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. … See more If the two side-chains on the central carbon are different from each other—either an aldoxime, or a ketoxime with two different "R" groups—the oxime can often have two different geometric stereoisomeric forms … See more The hydrolysis of oximes proceeds easily by heating in the presence of various inorganic acids, and the oximes decompose into the corresponding ketones or aldehydes, and hydroxylamines. The reduction of oximes by See more Oximes can be synthesized by condensation of an aldehyde or a ketone with hydroxylamine.
