Polycyclic molecules and tetrahydroquinoleines were obtained in a tandem reaction involving the diastereoselective addition of α-aminoalkyl radicals to (5 R)-5-menthyloxy-2 [5 H]-furanone 1. The facial diastereoselectivity on 1 is≥ 90%. The α-aminoalkyl radicals were produced from tertiary amines by photochemical-induced electron transfer. When N, N- dialkylanilines 19 were used as starting tertiary amines, a rearomatization step was ...
