title: Rhodium-catalyzed asymmetric reductive cyclization of heteroatom-linked 5-alkynals with heteroatom-substituted acetaldehydes.
abstract: We have established that a cationic rhodium(I)/H(8)-BINAP complex catalyzes the asymmetric reductive cyclization of heteroatom-linked 5-alkynals with heteroatom-substituted acetaldehydes in good yields with outstanding enantioselectivity.
