文摘Attempts to collective synthesis of the monoterpene indole alkaloids, isolated from Nauclea species, were examined by using asymmetric conjugate addition with Evans'chiral auxiliary as key step. However, only the H-15 and H-3 cis product 13 was obtained, which enabled us to achieve the asymmetric total synthesis of 3-epi-naucleamide A. The results indicate that this synthetic route can be applied in the synthesis of vincosamide.
