bofuranosyl}imidazolidine (3), and the benzamide 20 of 1-amino-2,5-anhydro-1-deoxy-3,4,6-O-tris-[((tert-butyl)dimethylsily)]-D-allitol. Compound 2 was converted efficiently into optically active tiazofurin (1).
(1 R,2 S,4 R)-2-氰基-7-氧杂双环[2.2.1]庚-5-烯-2-基(1 S ')-樟脑酸酯(5)被转化为(-)-甲基2,5-脱水-3,4,6- O-三[(叔丁基)二甲基甲硅烷基] -D-丙二酸酯(2),(+)-1,3-二苯基-2- 2',3', 5′- O-三[[叔丁基)二甲基甲硅烷基]-β-D-呋喃呋喃糖基}咪唑烷(3)和1-氨基-2,5-脱水-1-脱氧-3,4,6的苯甲酰胺20 - ö -三- [((叔丁基)dimethylsily)] - d-蒜糖醇。将化合物2有效地转化为旋光性噻唑啉(1)。
