Asymmetric total synthesis of the myxobacteria metabolites crocacins A–D
摘要:
The total syntheses of crocacins A-D are described. The key steps were a syn-aldol reaction followed by anti-reduction to secure the stereo-tetrad and acylation of an ene- or dienecarbamate to form the enamide. Crown Copyright (C) 2008 Published by Elsevier Ltd. All rights reserved.

[structure: see text] The first asymmetric synthesis of (+)-crocacin D (4) is described. The key steps in the sequence are the stereoselective assembly of the stereotetrad via a substrate-controlled aldol reaction and anti-selective reduction, formation of the (E,E)-diene by a Stille cross-coupling between the stannane 8 and vinyl iodide 9, and the acylation of (Z)-enecarbamate 6 with the acid chloride
