A formal enantioselective synthesis of nectrisine, a potent α-glucosidase inhibitor, was carried out starting from butadiene monoepoxide through a synthetic sequence involving enantioselective allylic substitution, cross-metathesis, dihydroxylation, and cyclization.

A short, stereoselective synthesis of the naturally occurring pyrrolidine radicamineB is reported. Garner's (R)-aldehyde, prepared from D-serine, was the chiral starting material. The pyrrolidine ring was stereoselectively created in a very efficient way through a five-step, one-pot transformation. In addition, an intermediate of this synthesis was transformed into an intermediate of a previously
An efficient and novel process is described for the synthesis of nectrisine 5 and its related derivatives 6,7 as potent glucosidase inhibitors via the corresponding lactams starting from D-(−)-diethyl tartrate. Also the results of biological evaluation of the synthesized compounds are described.
