Trans-ACPC with (15,25) configuration was prepared in an elegantly short pathway (Scheme 13) by Enders et al. By addition of the chiral ammonia equivalent lithiated (5)-(-)-2-methoxymethyl-1 -trimethylsilylaminopyrro-lidine (TMS-SAMP) to co-halide-substituted enoate 84, followed by Michael-initiated ring closure (MIRC), 85 was formed with 96-98% diastereoselectivity (Scheme 13). After desilylation,...
