A concise, convergent racemic synthesis of BMS-708163 is reported. Two fragments consisting of N-4-chlorophenylsulfonyl-3,3,3-trifluorpropylglycine and a 1,2,4-oxadiazole derivative of 2-fluorobenzyl alcohol were prepared in separate pots and then coupled together via a Mitsunobu reaction. Since a convenient chiral synthesis of optically pure (d)-3,3,3-trifluoropropyl glycine methyl ester was developed
据报道,BMS-708163的简明,会聚外消旋合成。在分开的罐中制备由N -4-氯苯基磺酰基-3,3,3-三氟丙基甘氨酸和2-氟苄醇的1,2,4-恶二唑衍生物组成的两个片段,然后通过Mitsunobu反应偶联在一起。由于使用Schöllkopf试剂烷基化开发了光学纯的(d)-3,3,3-三氟丙基甘氨酸甲酯的便捷手性合成方法,因此该方法也可用于BMS-708163的对映选择性合成。
