摘要:
As reaction products of canthaxanthin (beta,beta-carotene-4,4'-dione) with m-chloroperbenzoic acid and O-2 two derivatives 1 and 2 with an ozonide moiety in the polyene chain have been isolated. They were identified by UV/Vis-, LC/MS- and one and two dimensional NMR analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.
