Synthesis of the 2-aza analogues of pyrrolizidine and spirooxindole-2-azapyrrolizidine hybrid, a spiro-tetracyclic scaffold possessing multiple contiguous stereocenters, by an exclusive regio-, chemo-, and diastereoselective multicomponent reaction in water is reported. This logical and didactical tactic has integrated the principles of an ideal organic synthesis, privileged substructure-based diversity-oriented

1-Propargyl-2,4-dioxoimidazolidine (Compound I) is a very useful intermediate for synthesizing insecticidal and acaricidal compounds of the pyrethroid type.
A method for producing this intermediate comprises reacting a lower alkyl ester of N-propargyl-N-lower alkoxycarbonyl glycine (Compound VI) with ammonia, either under pressure or additionally with another base.
Alternatively Compound VI may be reacted with ammonia to form N-propargyl-N-lower alkoxycarbonyl glycinamide (Compound VII), which Compound VII is then reacted with a base to form the Compound I.
1-丙炔基-2,4-二氧代咪唑烷(化合物 I)是合成拟除虫菊酯类杀虫杀螨剂的一种非常有用的中间体。
生产这种中间体的方法包括将 N-丙炔基-N-低级烷氧基羰基甘氨酸的低级烷基酯(化合物 VI)与氨反应,可以在加压下进行,也可以另外与另一种碱反应。
或者,化合物 VI 与氨反应生成 N-丙炔基-N-低级烷氧基羰基甘氨酰胺(化合物 VII),然后化合物 VII 与碱反应生成化合物 I。
