An efficient and practical synthesis of kifunensine thioanalogs 1a-c was reported. The bicyclic azasugars fused thiazolidin-4-one 4a-c as key intermediates were first synthesized in good yields of 74-80% viaone-pottandemStaudinger/aza-Wittig/cyclization by using the pivotal azidosugars 3a and 3b derived from D-mannose. Followed by double Pummerer rearrangements and deprotection, the target thiokifunensine
