    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.

  • A Non-Aldol Preparation of Enantiopure Propionate-Derived Motifs with the Assistance of Chiral Sulfoxides: Application to a Convergent Synthesis of the Lactone Core of Octalactins

    anti configuration. As an application of this work, we have described an enantioselective synthesis of the unusual eight-membered lactone ring of the octalactins. Two propionate-derived fragments were coupled to give precursor 18, which was subjected to Yamaguchi's macrolactonisation to give the required lactone ring.

    approach to the synthesis of medium-ring lactones is reported based on sequential Evans-Tishchenko and ring-closing metathesis (RCM) reactions. High diastereoselectivity (>95:5) is demonstrated in the Evans-Tishchenko reaction of unsaturated aldehydes with unsaturated beta-hydroxy ketones, and conditions for the RCM cyclization of the resultant dienes have been optimized to give high yields of medium
