Application of Mitsunobu Reagents to Redox Isomerization of CF3-Containing Propargylic Alcohols to (E)-α,β-Enones
摘要:
Isomerization of CF3-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.
