APPLICATION OF THE NEW ACYLATING AGENTS TO THE SYNTHESIS OF INDOLE ALKALOIDS. A TOTAL SYNTHESIS OF (+/-)-ASPIDOFRACTININE

The new acylating agents were proved to be useful for introduction of an acetyl group into the α-position of the carbonyl group by means of two-carbon Michael acceptors, which was successfully applied to
