SYNTHESIS OF 4-AMINO-1,2-HYDROCARBYL PYRAZOLIDINES VIA 4- NITRO ANALOGS

4-Nitro-1,2-hydrocarbyl pyrazolidines are prepared by a novel route from 1,2-disubstituted hydrazines and 1,3-di-(secondary amino)-2-nitropropanes and reduced to the corresponding 4-amino-1,2-hydrocarbyl pyrazolidines, which latter compounds are intermediates in the preparation of certain pharmaceut...
