  Diastereoselective synthesis of (+)-nephrosterinic acid and (+)-protolichesterinic acid

  摘要：

  A diastereoselective synthesis of (+)-nephrosterinic acid and (+)-protolichesterinic acid, common members of the paraconic acids is described. The synthesis is based on a diastereoselective orthoester Johnson-Claisen rearrangement of a (Z)-allyl alcohol with a vicinal dioxolane moiety as key steps. The synthesis is completed in 10 steps and with overall yields of 15.9% for (+)-nephrosterinic acid and 16.4% for (+)-protolichesterinic acid. (C) 2012 Elsevier Ltd. All rights reserved.

  日期：2011.2

  efficient stereoselective total synthesis of (+)-nephrosteranic acid and (+)-roccellaric acid is presented. The synthetic strategy features the regioselective asymmetric dihydroxylation of the γ,δ-olefinic bond of a α,β,γ,δ-unsaturated ester and the Johnson–Claisen rearrangement as the key steps. The synthesis is achieved in 10 steps and 6.8 % (nephrosteranic acid) and 7.6 % (roccellaric acid) overall
