  Enantioselective synthesis of (S)- and (R)-mappicines and their analogues

  摘要：

  The naturally occurring alkaloids, camptothecin and mappicine ketone were converted to racemic mappicine acetate which was enantioselectively hydrolyzed to (S)- and (R)-mappicines in high optical purity using baker's yeast and a lipase, Amano PS. Treatment of the racemic acetate with baker's yeast afforded (S)-mappicine while with Amano PS yielded (R)-mappicine. 9-Methoxycamptothecin and 9-methoxymappicine ketone underwent similar conversion to (S)- and (R)-9-methxymappicines.

• Acetylation of Camptothecins Using Lithium Bromide as Catalyst

  Camptothecin and 9-Methoxycamptothecin, two promising naturally occurring anticancer alkaloids containing a tertiary hydroxy group, were acetylated with acetic anhydride at room temperature in the presence of lithium bromide as catalyst. The similar method was followed for acetylation of other two related natural alkaloids, mappicine and 9-methoxymappicine.
