Abstract

A general stereoselective synthesis of 4.5-dihydroxy-2-alkene esters is developed using the photo-induced rearrangement of α, β-epoxy diazomethyl ketones. Starting with readily available enantiopure allylic alcohols that contain a chiral center at C4, ie a protected secondary alcohol function, a neighboring stereogenic center is introduced by irradiation of the mentioned diazo ketones. The configuration of this newly introduced center is ...
