CommunicationDiastereo- and enantioselective palladium-catalyzed dearomative [4 + 2] cycloaddition of 3-nitroindoles

Add time:08/29/2019    Source:sciencedirect.com

A Pd-catalyzed asymmetric decarboxylative [4 + 2] cycloaddition of 3-nitroindoles and vinyl benzoxazinanones is developed through a dearomatization approach. The reaction provides an efficient protocol for constructing a series of chiral tetrahydro-5H-indolo[2,3-b]quinolines in high yields and with excellent diastereo- and enantioselectivities.
