摘要:
An expedient enantioselective synthesis of highly substituted hydrocarbazoles has been realized by an organocatalyzed formal [3 + 3] cycloaddition between acrolein and 2,3-disubstituted indoles. Tricyclic hydrocarbazoles were obtained from a broad range of 2,3-disubstituted indoles and acrolein in good to excellent yields and excellent enantioselectivites.
