Title: Formal Synthesis of Premisakinolide A and C(19)-C(32) of Swinholide A via Site-Selective C-H Allylation and Crotylation of Unprotected Diols. Author: Shin I, Krische MJ. Journal: Org Lett; 2015 Oct 02; 17(19):4686-9. PubMed ID: 26375150. Abstract: Using stereo- and site-selective C-H allylation and crotylation of unprotected diols, an intermediate in the synthesis of premisakinolide A (bistheonellic acid B) that was previously made in 16-27 (LLS) steps is now prepared in only nine steps. This fragment also represents a synthesis of C(19)-C(32) of the actin-binding macrodiolide swinholide A.[Abstract] [Full Text] [Related] [New Search]
