  Formal Total Synthesis of Salicylihalamides A and B

  摘要：

  An efficient synthesis of the macrolactone 3 of the salicylihalamides in 10 linear steps from alkene 6 is described. The key steps involved a Stille coupling between the chiral stannane 5 and benzyl bromide 4, which produced alkene 15 in good yield, and subsequent base-induced macrolactonization then gave compound 3. Macrolactone 3 was then converted into the known salicylihalamide A intermediate 18 in a three-step sequence. Compound 3 was also converted into another known salicylihalamide A and B intermediate 23 in a five-step sequence.
