A facile one-pot synthesis of novel steroidal dispiropyrrolidines has been accomplished by 1,3-dipolarcycloaddition reaction of various azomethineylides derived from isatin/acenaphthenequinone/ninhydrin and sarcosine with various estrone derivatives as dipolarophiles, in good yield. The effect of various solvents on the 1,3-dipolarcycloaddition reaction are also studied.
