A Convenient One-Pot Completely Stereoselective Synthesis of trans-4-Hydroxystilbenes and Its Derivatives and X-Ray Structure of Its Precursor

Abstract

The synthesis of E-isomer of 4-Hydroxystilbene and its derivatives 3 by reductive elimination of the carbonyl function in 2-phenyl-1-(4-hydroxyphenyl)ethan-1-one and its derivatives 2 and the X-ray structure of 2a are described.

Keywords:

• Stereoselective
• trans-4-Hydroxystilbene
