Synthesis of bridged bicyclic hydrazines via endocyclic N-acylhydrazonium intermediates: A novel route to the 1-Azatropane skeleton

Construction of enantiopure imine bridged benzo[c]azepinones by a silver(i) and chiral N-heterocyclic carbene multicatalytic reaction sequence of N′-(2-alkynylbenzylidene)hydrazides and cyclopropanecarbaldehydes

A novel and efficient method for the synthesis of enantiopure bridged benzo[c]azepinone compounds has been developed by metal/N-heterocyclic carbene multicatalysis.

Stereoselective synthesis of 2,3-disubstituted indoline, pyrrolidine and cyclic ether-fused 1,2-dihydroquinoline derivatives using alkyne iminium ion cyclization of vinylogous carbamates: switch of regioselectivity using an internal hydroxy group as a nucleophile

TMSOTf promoted alkyne iminium ion cyclization of vinylogous carbamates gives stereoselective access to indolines, pyrrolidines and dihydroquinolines.
