The reaction of a 2-(1-benzotriazolyl)vinamidinium salt with Grignard reagents to yield alpha,beta-unsaturated aldehydes with stereochemical control is described.
A three step synthesis of a novel 2-(1-benzotriazolyl)-vinamidinium salt is described along with its direct conversion to a series of unusual 5-(1-benzotriazolyl)pyrimidines, 4-(1-benzotriazolyl)-pyrazoles, and 4-(1-benzotriazolyl)pyrroles.
