✦ Synopsis
tion 17 July lY75) Previously we have reported that the reaction of C-phenyl-N-methyl nitrone with sodio triethyl phosphonoacetate leads to the formation of two isomeric asiridines.l In this communication we wish to describe results obtained in our study of the reactions of 5,5-dimethyl-Al-pyrroline N-oxide (I;> with two phosphonates: (Et0)2P(O)CH2C02Et (2a) and (Et0)2P(O)CH2CN (2b). Reactions of nitrone 1 with the phosphono ylids generated from & and &with sodium hydride in 1,2-dimethoxyethane (DME) gave the &runs-aziridines h and &.
