Özet:

Chiral cyclic alkenols with hydroxymethyl functionality are important structural units in many biologically active natural compouds such as prostaglandins, sesquiterpene antiviral agents, pentenomycins, xanthocidin, sarkomycin, etc. 1,3-cycloalkanediones are converted into bicyclic polyoxo derivatives with formaldehyde and trioxane in the presence of Lewis acid. Selective oxidation of the bicyclic compounds by using manganese(III)acetate followed by enzyme-catalyzed kinetic resolution afforded chiral bicyclic hydroxy ketones. Reduction of carbonyl group and cleavage of the ether functionality furnished the desired chiral cycloalkanols with hydroxymethyl group. This study is a model for the synthesis of these type of compounds.
