6-dihydro-4H-oxazines and thiazines, 4,5-dihydro-3H-benzo[c]azepine, and 3,4-dihydroisoquinoline, to produce diverse products instead of β-sultam derivatives. The results indicate that alkanesulfonyl chlorides react with cyclic imines to generate N-alkanesulfonyl cyclic iminium ions, which are attacked by nucleophiles, such as water and chloride anion, in the reaction systems, affording addition products
摘要 虽然烷烃磺酰氯与线性亚胺反应生成 β-磺胺衍生物,但在本研究中,它们与各种环状亚胺反应,包括 1-吡咯啉、恶唑啉、5,6-二氢-4H-恶嗪和噻嗪,4, 5-二氢-3H-苯并[c]氮杂和3,4-二氢异喹啉,用于生产多种产品,而不是β-舒坦衍生物。结果表明,烷烃磺酰氯与环状亚胺反应生成N-烷烃磺酰基环状亚胺离子,在反应体系中受到水和氯阴离子等亲核试剂的攻击,生成加成产物。亚胺中间体不能通过闭环形成β-舒坦衍生物。芳烃磺酰氯与环状亚胺反应时表现出类似的行为。研究了磺酰氯与亚胺反应的范围和局限性。图形概要
