Application of Mitsunobu reagents to redox isomerization of CF3-containing propargylic alcohols to (E)-α,β-enones.

Yohsuke Watanabe1, Takashi Yamazaki.   

Abstract

Isomerization of CF(3)-containing secondary propargylic alcohols proceeds with excellent E selectivity by treatment with Mitsunobu reagents, tris(p-methoxyphenyl)phosphine (TMPP), and 1,1'-(azodicarbonyl)dipiperidine (ADDP) in the presence of phenol.
