标 题 :Metal-catalyzed arylations of hydrazines, hydrazones, and related substrates
发明人：BUCHWALD STEPHEN L; WAGAW SEBLE; GEIS O
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:A method is provided for the transition metal-catalyzed arylation, or vinylation, of hydrazines, hydrazones, and the like. Additionally, the invention provides a conceptually novel strategy, the cornerstone of which is the transition metal-catalyzed arylation or vinylation method, for the synthesis of indoles, carbazoles, and the like. The methods and strategies of the invention may be utilized in standard, parallel, and combinatorial synthetic protocols.

标 题 :Synthesis of 4-amino-1,2-hydrocarbyl pyrazolidines via 4-nitro analogs
发明人：LO YOUNG SEK; MUNSON HARRY RANDALL JR
权利人:ROBINS CO INC A H
摘要: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 pharmaceutical benzamides. n The novel 4-nitro-1,2-hydrocarbyl pyrazolidines have the formula: ##STR1## wherein R 1 and R 2 are selected from loweralkyl, lowercycloalkyl or phenyl-loweralkyl and may be the same or different.
