Structural aspects in naturally occurring phenolics using 1H nmr acylation and alkoxylation shifts

HEMLATA ., S B KALIDHAR

Abstract


The trends for IH nmr acylation shifts [triangleH(OAc OH)] have been shown to be similar to those for alkoxylatlon [AH(OAc OMe)] and glycosyloxylation [triangleH(OAc O-gly Ac)] Shifts this observation is helpful for structural determination in naturally occurring phenolics.

Keywords
