Reaction of 4-trimethylsilyl-3-buten-1-ols with aldehydes under mild Lewis acid conditions gives substituted dihydropyrans in excellent yields and with good stereocontrol.
An efficient method for stereoselective nitroaminoxylation of alkyne has been reported. The reaction enjoys a broad substrate scope, good functional group tolerance, and high yields. Synthetically useful α-nitroketones can be accessed through these products in a single step.
