An enantioselective total synthesis of (-)-decarbamoylsaxitoxin (2) has been accomplished, using the asymmetric trimolecular cyclization of 6, i.e., 6 + (R)-glyceraldehyde 2,3-acetonide + Si(NCS) 4 → α-7, as the key step. The structure of the major product α-7 was determined by X-ray crystallographic analysis, with the C-6 configuration corresponding to the unnatural antipode of decarbamoylsaxitoxin
