The first syntheses of the polyhydroxylated alkaloids (iminosugars) broussonetines O and P, glycosidase inhibitors of the pyrrolidine class, have been performed in a convergent, stereocontrolled way from d-serine as the chiral starting material. The synthesis of broussonetin C, a further member of this compound family, is also reported. A cross-metathesis step was one key feature of the synthesis.
吡咯烷类的糖苷酶抑制剂多羟基化生物碱(亚氨基糖)布鲁内斯汀O和P的首批合成方法是从d-丝氨酸作为手性起始原料,以收敛,立体控制的方式进行的。还报道了该化合物家族的另一成员布鲁索菌素C的合成。跨复分解步骤是合成的关键特征之一。所选合成概念的多功能性使该化合物家族的许多成员均可使用,包括天然的及其类似物。
