New method for the synthesis of pyrrolo[2,3- b ]dihydroquinolines
摘要:
Intramolecular cyclization of [2-(2-chloroquinolin-3-yl)ethyl]amines, formed in situ from the reaction of N-phthaloyl-protected [2-(2-chloroquinolin-3-yl)ethyl]amines and hydrazine hydrate gave pyrrolo [2,3-b]dihydroquinolines in high yields. (C) 2015 Elsevier Ltd. All rights reserved.

Azide-methylenecyclopropanes (azide-MCPs) underwent intermolecular cyclization with isonitriles catalyzed by RhII complex has been disclosed in this paper, producing a series of pyrrolo[2,3-b]quinolines in moderate to good yields via carbodiimide intermediates....
denitrogenative C(sp3)-Hamination of 1,2,3,4-tetrazoles bearing unactivated primary, secondary and tertiary C-H bonds is discovered. This cata-lytic amination follows an unprecedented metalloradical activation mechanism. The utility of the developed method is showcased with the short synthesis of a bioactive mole-cule. Moreover, an initial effort has been embarked for the enantioselective C(sp3)-H amination
