Total synthesis of (+)-pericosine B and (+)-pericosine C and their enantiomers by using the Baylis-Hillman reaction and ring-closing metathesis as key steps

A simple and divergent route for the total synthesis of pericosine B and pericosine C and their enantiomers from D-ribose by using the Baylis-Hillman reaction and ring-closing metathesis reactions as key steps has been described. (C) 2011 Elsevier Ltd. All rights reserved.
