The Wittig reaction of quinisatines (1a,b) with 1-ethoxycarbonylethyliden- (2a) and ethoxycarbonylmeth-ylenetriphenylphosphorane (2b) has been investigated. In both cases unusual reaction products (3a,b and 12a,b respectively) were isolated in high yields and converted to potential antiinflammatory acids 6, 8, 15 and lactones 4, 7.
研究了奎尼丁(1a,b)与1-乙氧羰基亚乙基- (2a)和乙氧羰基甲基-亚乙基三苯基磷烷(2b)的维蒂希反应。在两种情况下不同寻常的反应产物(3A,3B和图12A,B分别)以高收率分离出,并转换成电位抗炎酸6,8,15和内酯4,7。
