摘要

The photoproducts 384 and their methylated derivatives ga-c, as well as the acetylation product of 3a, show in the mass spectrum an efficient cleavage of OH, OCH3, or OCOCH3, respectively, which is followed by decarbonylation to give an ion of the probable structure A. In a similar pattern the carbinols 12b
