Disclosed is a process for producing a β-nitroenamine compound represented by the formula I:
wherein R₁ and R₂ are the same or different and independently indicate a hydrogen atom or a straight-chain or branched C₁-C₁₀ alkyl group which may be optionally substituted with at least one group selected from the group consisting of a halogen atom, a lower alkoxy group, an aryloxy group, hydroxyl group or an aryl group, or an aryl group which may be optionally substituted with at least one group selected from the group consisting of a halogen atom, a lower alkyl group, a lower alkoxy group, an aryl group, an aryloxy group, a nitro group, a cyano group, an acylamino group, a lower dialkylamino group, an arylamino group, a hydroxyl group, an arylsulfonyl group, a mercapto group, a lower alkylthio group or an arylthio group, and R₁ and R₂ may bond together to form a cycloalkyl or bicycloalkyl group; and R₃ is a hydrogen atom, a lower alkyl group, a cycloalkyl group or an aralkyl group; and an intermediate for producing the β-nitroenamine compound.
本发明公开了一种生产由式 I 代表的 β-硝基烯胺化合物的工艺:
其中R₁和R₂相同或不同,且独立地表示氢原子或直链或支链C₁-C₁₀烷基,该烷基可任选被至少一个选自由卤素原子、低级烷氧基、芳氧基、羟基或芳基组成的组中的基团取代,或可任选被至少一个选自由卤素原子、低级烷氧基、芳氧基、芳氧基、羟基或芳基组成的组中的基团取代的芳基、低级烷基、低级烷氧基、芳基、芳氧基、硝基、氰基、酰氨基、低级二烷基氨基、芳氨基、羟基、芳磺酰基、巯基、低级烷硫基或芳硫基,且 R₁ 和 R₂ 可键合在一起形成环烷基或双环烷基;和 R₃ 是氢原子、低级烷基、环烷基或芳烷基;以及生产 β-硝基烯胺化合物的中间体。
