Abstract
The stereochemistry of SN2 and SN2′ substitutions of the allylic mesyloxy group in mesylates of prostaglandin allylic epimeric 13- and 15-alcohols under the action of various nucleophiles (H2O, MeOH, AcOH, LiBr) was studied. The substitution accompanied by rearrangement occurs with moderate (1.4–1.6 : 1) syn-stereoselectivity with respect to the configuration of the mesyloxy group, which increases with decreasing temperature and depends only slightly on the nature of the nucleophile.
