  Model Studies on the Synthesis of Madangamine Alkaloids. Assembly of the Macrocyclic Rings

  摘要：

  Using simplified model derivatives, the assembly of the macrocyclic rings of madangamines, including the 13- and 14-membered D rings of madangamlnes C-E, the all-cis-triunsaturated 15-membered D ring of madangamine A, and the (Z,Z)-unsaturated 11-membered E ring common to madangamines A-E, has been studied.

  Selective syn-epoxidation of C=C double bonds in primary and secondary alkenylammonium arenesulfonate salts 3H(+), to give the corresponding epoxyalkylammonium salts 4H(+), has been achieved by reaction with electrophilic O-transfer reagents such as m-CPBA, methyl(trifluoromethyl)dioxirane (TFDO), and dimethyldioxirane (DMDO). Epoxyalkylamines 4 are easily obtained in high yields from the corresponding epoxyalkylammonium salts 4H(+) by simple deprotonation with sodium carbonate. The ammonium group deactivates the C=C double bond, and hence the epoxidation rate is slower than in the case of simple olefins. II-Bonding interaction between the ammonium group and the O-transfer reagent(m-CPBA and DMDO) in the transition state is claimed to account for the rate enhancement and diastereoselectivity observed when the necessary conformational requirements are established. The allylic ammonium group is shown to be very efficient in directing the epoxidation with m-CPBA and DMDO on the syn-diastereoface.
