Diastereoface differentiating peracid oxidation of the enol ether derived from cyclohexanone and 2,4-pentanediol: Preparation of optically pure 2-hydroxycyclohexanone acetal
Diastereoface differentiating m-chloroperbenzoic acid oxidation of the chiral enol ether prepared from cyclohexanone and optically active 2,4-pentanediol proceeded from -72 to 39-degrees-C to give a diastereomeric mixture of the corresponding 2-hydroxycyclohexanone acetal. The diastereomeric excess of the product reached almost 100 % at -72-degrees-C.
