摘要

Treatment of 3 with N-bromosuccinimide yields 1. Simple addition-elimination reactions of 1 and the related ketone 6 give 9, 10, 11, and 14. Enedione 1 is a sluggish dienophile relative to the parent compound 18, but it behaves as a normal dipolarophile. The mechanistic implications of these observations are noted and the structure and stereochemistry of adducts of 1 with cyclopentadiene, three anthracenes, two aairidines (24 and 25), and ...
