Reaction of 4-trimethylsilyl-3-butenyl-1-amines with aldehydes under mild Lewis acid conditions gives substituted tetrahydropyridines in excellent yields and with excellent trans diastereoselectivity.

A versatile and high-yielding indium trichloride mediated cyclization reaction of silylated homoallylic alcohols, thiols, or amines with aldehydes or epoxides is described as a rapid route to a range of unsaturated heterocycles. The excellent diastereoselectivity observed offers a method of wide scope and generality.

Synthesis of Nitrogen- and Oxygen-Containing Heterocycles by Prins Cyclization in Continuous Flow
are described for the synthesis of the corresponding tetrahydropyridines and pyran derivatives, respectively. In particular, the use of pyridine-carboxaldehydes for aza-silyl-Prins reaction led to either a symmetrical triarylmethane or two new bicyclic compounds. 4-Fluorinated-2-substituted tetrahydropyranderivatives were also obtained in the oxa-Prins cyclization with good selectivity in favor of
