2,2-Bis-(ethoxycarbonyl)-3,4-dihydro-2H-pyrroles are prepared from conjugated enones and diethyl aminomalonate by a one-step cyclocondensation reaction. Reduction of the products with sodium cyanoborohydride affords the corresponding pyrrolidines.
2,2-双-(乙氧基羰基)-3,4-二氢-2H-吡咯由共轭烯酮和氨基丙二酸二乙酯通过一步环缩合反应制备。用氰基硼氢化钠还原产物得到相应的吡咯烷。
