A newclass of pharmacologically interesting compounds has been synthesized through a novel SN2 dispalcement of the CF3SO2 group in benzyl 2,3-anhydro-4-trifluoromethylsulphonyl-α-D-ribopyranoside (1) and its β-L-isomer (2), by a variety of suitably protected naturally occurring aminoacids: the reaction pathway also provides an efficient route to benzyl 2,3-anhydro-β-L- and -α-D-lyxopyranosides [(3)
一类新的药理学上感兴趣的化合物已经通过一种新颖的合成小号Ñ的CF 2 dispalcement 3 SO 2在苄基2,3-脱水-4-三氟甲基磺酰基- α- d -ribopyranoside(1)和它的β-大号-异构体(2),可以通过各种适当保护的天然存在的氨基酸来实现:反应途径还提供了通往2,3,3-脱水-β - L-和-α - D- lyxopyranosides [(3)和(4)的有效途径) 分别]。
