3-Azabicyclo[3.1.0]hexane -2,4-dione and substituted analoguesthereof can be prepared by reacting a compound of the general formula II or a halide, ester or anhydride thereof:-
in which each of R1, R2, R3 and R4 represents a hydrogen atom or an optionally alkoxy-substituted alkyl, alkenyl, aryl, alkaryl or aralkyl group, with ammonia and optionally water, and effecting cyclisation of the resultant intermediate product by heating. Most of the compounds prepared are novel.
3-氮杂双环[3.1.0]己烷-2,4-二酮及其取代的类似物可通过通式 II 的化合物或其卤化物、酯或酸酐与氨反应制备
其中 R1、R2、R3 和 R4 各代表一个氢原子或一个任选由烷氧基取代的烷基、烯基、芳基、烷芳基或芳烷基,与氨和任选的水反应,并通过加热使生成的中间产物环化。所制备的大多数化合物都是新型的。
