Abstract
An efficient stereoselective synthesis of 2,6-disubstituted-4-thiocyanatotetrahydropyrans has been developed through a one-pot three-component reaction of aldehydes, trimethyl allylsilane, and NH4SCN in the presence of BF3.Et2O at room temperature. The products are formed rapidly (10-30 min) in excellent yields (78-98%).
Keywords: Aldehydes, allyl trimethylsilane, lewis acid, prins cyclization, thiocyanatotetrahydropyran, one-pot reaction.

Impact of Organocatalysis on Homogeneous and Heterogeneous Catalytic Organic Synthesis: Recent Advances and Developments
Catalysis is vital in improving the reaction time, conversion, selectivity, and yield of organic and biological reactions. Heterogeneous and homogeneous catalysis have developed many types of catalysts to perform different organic and industrial reactions. In recent decades, researchers have tried to perform the reactions in a greener and more sustainable ...read more
