I'm confused since there are thousands of papers about enantioselective transesterification of alcohols with vinyl actetate or other acylating agent.
Depending on paper the reaction is reffered to acylation or acetylation. It is acetylation, isn't it?

A) Transesterification itself is not enantioselective, unless the alcohol you're using is optically pure.  But that has nothing to do with the process itself.

B) Acetylation is a specific type of acylation.  You can acylate with lots of different compounds.  When you add an acetate group specifically, that's acetylation.
