Lutein (14), as diacetate, upon epoxidation with w-chlorperbenzoic acid gave a minor epoxide identical with lutein epoxide (46) diacetate besides the major 3,5-cis epoxide (46). In a similar way zeaxanthin (26) diacetate had previously been converted to violaxanthin (32) diacetate (20), the 3,5- and 3, 5 -Irons compounds being obtained as minor products in addition to the major 3,5- and 3, 5 -cis derivatives, consistent with results for simple model compounds (20) and subsequent NMR data (78).
