A tandem ring-closing/cross-coupling metathesis reaction toward the short synthesis of goniothalamin analogs

Bruder, Marjorie ; Pilli, Ronaldo Aloise ;

Abstract:

In view of preparing furanone analogs – exemplified by compound 1- of the cytotoxic naturally occurring styryl lactone goniothalamin (2), we envisioned a key cross-coupling metathesis reaction between vinyl furanone 3 and a range of styrenes. Inspired by the work of Piva et al, where 3 would be formed in situ via ring-closing metathesis of triene 4, we herein report the short synthesis of a variety of styryl furanones using a key tandem ringclosing/ cross-coupling metathesis (RCM/CCM) step.
