NMR CHARACTERIZATION OF KETO-ISOPHORONE KETALS

Abstract

Abstract:

In this paper，NMR characteristics of two keto-isophorone ketals were reported. By comparing with the NMR spectra of the compound (2)
reported in the references and with the NMR spectra of ketoisophorone itself， the ¹H and ¹³C chemical shifts of keto-isophorone ketal (3) were assigned and analyzed and its structure was determined.

Key words: NMR, assignment, keto-isophorone, ketal, structure

CLC Number:

O641
