6-dideoxy-L-idofuranose derivatives, respectively. The corresponding 2-thioxo-(4R)- and -(5S)-thiazolidine derivatives (11 and 13) were also synthesized from 5,6-dideoxy-5,6-epimino-L-idofuranose and 6-azido-6-deoxy 5-O-tosyl-D-glucofuranose derivatives, respectively. 2-S-Methylated derivatives of 11 and 13 were reduced with aluminum amalgam to give the corresponding (4R)- and (5S)-thiazolidine derivatives, respectively
2-Aryl-(5S)- 和 -(4S)-(3'-O-benzyl- 和 3'-O-methyl-1',2'-O-isopropylklene-α-D-xylo-tetrofuranos-4' -yl)-2-恶唑啉 (3 和 7) 由 6-aroyamido-6-deoxy-5-O-tosyl-D-glucofuranose 和 5,6-aroylepimino-5,6-dideoxy-L-idofuranose 衍生物制备,分别。相应的 2-thioxo-(4R)- 和 -(5S)-噻唑烷衍生物(11 和 13)也由 5,6-dideoxy-5,6-epimino-L-idofuranose 和 6-azido-6-deoxy 合成分别为 5-O-甲苯磺酰基-D-呋喃葡萄糖衍生物。11和13的2-S-甲基化衍生物用铝汞齐还原,分别得到相应的(4R)-和(5S)-噻唑烷衍生物。11分子内半
