In this study, we achieved the first totalsynthesis of (+)-heteroplexisolideE. The synthetic highlights of our approach include a one-pot regioselective methylation method and the transformation of a β-methallyl alcohol moiety to a prenyl group using palladium-catalyzed hydrogenolysis.

An enantioselective first totalsynthesis and structural revision of the cytotoxic natural product amphidinolide W is described. We initially investigated a ring-closingmetathesisbased synthetic strategy to form the 12-membered macrocycle. This strategy was unsuccessful as it led to formation of a 17-membered macrocycle. Subsequently, we explored an alternative strategy that involved cross-metathesis

[reaction: see text] A convergent approach to the synthesis of the bis-tetrahydrofuran (THF) components of the nonadjacently linked THF-containing acetogenins is illustrated in the synthesis of 2, a potential intermediate for the antitumor agent bullatanocin (squamostatin C). The plan centers on the olefin cross-metathesis of THF allylic alcohol derivatives 3 and 4 as the key segment coupling step

The first total synthesis of phomopsolidone B and the total synthesis of phomopsolidone A have been achieved based on an olefin cross-metathesis approach starting from L-(+)-diethyl tartrate. (C) 2016 Elsevier Ltd. All rights reserved.
