Process for isomerizing c-22 iodovinilderivados by photoisomerization.

摘要

Process for isomerizing compounds of general structure (II) to compounds of general structure (1) where R {sub, 1} and R {sub, 2} represent hydrogen or a hydroxyl protecting group, comprising a photoisomerization compound of structure General (II) with a UV lamp, with a reaction volume comprised between 50 ml and 500 ml, at a temperature between -15 and 45 ° C, and reaction times between 0.5 minutes and 20 minutes.
