  Studies Directed toward the Synthesis of (+)-Sesbanimide A: Construction of the AB-Ring System (A Formal Total Synthesis)

  摘要：

  Complete details of a study leading to the asymmetric synthesis of the AB-ring system of (+)-sesbanimide A (1), a potent cytotoxic agent belonging to the class of sesbania alkaloids, are described. Key features of the synthesis include (a) the stereoselective introduction of the C8 and C9 hydroxyl groups through the use of a diastereoselective catalytic osmylation of enantiomerically enriched alpha-alkoxy allylsilanes and (b) a chelation-controlled nucleophilic addition of a vinyl Grignard reagent to a syn alpha-alkoxy beta-(silyloxy) aldehyde for the introduction of the C7 stereocenter required for assembly of the B-ring.

  ylsilanes of structural type 1, bearing benzyl, benzyloxymethyl (BOM) ether protecting groups can be efficiently and selectively desilated to produce the corresponding aldehydes 2 by catalytic hydrogenolysis over 10% palladium on carbon in ethanol or ethyl acetate.

  带有苄基，苄氧基甲基（BOM）醚保护基的结构类型为1的正-α，β-二烷氧基-酰基二甲基苯基硅烷可通过在乙醇或乙酸乙酯中的10％钯/碳上进行催化氢解反应，有效而选择性地脱硅生成相应的醛2。
