Enantiospecific synthesis of (+)-N(a)-methylpericyclivine and (-)-N(a)-methylakuammidine as well as the ring-A oxygenated natural products, (+)-10-methoxy N(a)-methylpericyclivine and 10-hydroxy N(a)-methylpericyclivine.
[reaction: see text] The first enantiospecific, regiospecific total synthesis of the enantiomers of N(a)-methylpericyclivine and N(a)-methylakuammidine as well as the ring-A oxygenated natural products (+)-10-methoxy N(a)-methylpericyclivine and 10-hydroxy N(a)-methylpericyclivine was achieved. The lactones (see 19, 22, and 25) are key to the formation of the beta-axial methyl ester moiety.
