A convenient and highly efficient method for the regio- and stereoselective addition of tertiary amines to electron-deficient alkenes has been elaborated. It is based on a radical chain reaction of α-aminyl radicals with alkenes, induced by a photoe

Photochirogensis, or photochemical induction of molecular chirality, is an attractive alternative to thermal or enzymatic asymmetric synthesis. Using the inherent advantage that the photochemical reaction is driven by light absorption, the effect of

Tertiary amines derived from pyrrolidines can be added very efficiently (isolated yields up to 94%) to (5R)-5-mentyloxy-2[5H]-furanone. The addition, which follows a radical chain mechanism initiated by a photoinitiated electron transfer (PET) from t
