The hydroxylactones 4a–b (both available in optically pure form from biocatalytic processes) have been used in the preparation of carbovir, 1592U89, and their six-membered ring analogues.
Iodocyclization and [3,3] sigmatropic rearrangement reactions of N-substituted carbonimidothioates are used to prepare valienamine (1), 7-nor-valienamine (8), and the valienamine-based pseudo-disaccharide 12.
