Significance

Intramolecular Friedel-Crafts-type α-arylation of aldehydes under SOMO catalysis has been reported. Using the secondary amine catalyst 1 and CAN as the oxidant, aldehydes 2 were obtained in good yields and with high enan­tioselectivity. An application of the method was demonstrated by the total synthesis of the anti­tumor natural product demethyl calamenene.
