标题:Reaction Of Dimethoxycarbene With Strained Cyclic Carbonyl Compounds
摘要:一种环丙酮,一种环丙烯酮,环丁酮,一种环丁二酮,以及一种环丁烯二酮与二甲氧基卡宾反应,通过将卡宾形式插入到羰基相邻的c-C键中,生成下一个更大环的缩醛.当两个饱和的α-环碳可能参与到过程中时,环扩展是选择性的,主要生成插入到更多取代的环键中的产物.使用2,3-二甲氧基环丁烯-1,2-二酮,插入发生在羰基之间,而使用β-丙内酯则发生在内酯键中.然而,β-丙内酰胺通过将卡宾插入n-H键中发生反应.关键词:β-丙内酯,环丁酮,环丁二酮,环丙酮,二烷氧基卡宾.

摘要:This invention provides compounds of formula: n n n in which R f is a radical that carries a perfluoromethylene group, which group ensures bonding to the remainder of the molecule; R1 and R3, which can be the same or different, are chosen from among hydrogen and alkyl or aryl radicals; Ψ is an electroattractor group such that Ψ-O—H is an acid whose pKa (in water) is at most equal to 8, advantageously 6, and preferably 5. These compounds are useful for the synthesis of nitrogen-containing heterocyclic compounds.
