A diversity-oriented synthesis is described for functionalized chiral building blocks (i.e., 7, 9, 10, 16, and 17) and the biologically active iminosugar, fucosidase inhibitor (2S,3R,4R,5R)-2-(hydroxymethyl)-5-methylpyrrolidine-3,4-diol (22), starting from common chiral intermediate 1a which is obtained through a regioselective reductive cleavage of a bis(benzylidene) acetal.
描述了功能化手性构件(即 7、9、10、16 和 17)和生物活性亚氨基糖、岩藻糖苷酶抑制剂 (2S,3R,4R,5R)-2-(羟甲基)-的面向多样性的合成5-甲基吡咯烷-3,4-二醇 (22),从常见的手性中间体 1a 开始,该中间体是通过双(亚苄基)缩醛的区域选择性还原裂解获得的。
