Organocatalytic enantioselective Friedel-Crafts alkylation of 4,7-dihydroindoles with α,β-unsaturated aldehydes: An easy access to 2-substituted indoles

Hong, Liang,Liu, Chunxia,Sun, Wangsheng,Wang, Lei,Wong, Kwokyin,Wang, Rui

, p. 2177 - 2180 (2009)

An enantioselective Friedel-Crafts alkylation of 4,7-dihydroindoles and α,β-unsaturated aldehydes has been developed. The process is promoted by diphenylprolinol ether to afford 2-substituted 4,7-dihydroindoles in high yields and enantioselectivities. Aft
