1-Chloroalkyl p-tolyl sulfoxides as useful agents for homologation of carbonyl compounds: conversion of carbonyl compounds to .alpha.-hydroxy acids, esters, and amides and .alpha.,.alpha.'-dihydroxy ketones
摘要:
One-carbon homologation of carbonyl compounds to alpha-hydroxy acids, esters, and amides by the use of 1-chloroalkyl p-tolyl sulfoxide as a hydroxycarbonyl anion equivalent is reported. Oxidation of the vinyl chlorides, the intermediates of the above-mentioned method, with osmium tetraoxide gives alpha,alpha'-dihydroxy ketones which are found in biologically active natural products such as cortisone and adriamycin.
