A new variation of Prins cyclization to directly and stereoselectively synthesize cis-2,6-disubstituted tetrahydropyran-4-ones from 3-chlorohomoallylic alcohols and aldehydes catalyzed by perrhenic acid is reported. The reaction is generally compatible with a range of aliphatic and aromatic aldehydes and 24 examples of tetrahydropyran-4-one products have been prepared in moderate to good yields. This

In the presence of metallic zinc, 2,3-dichloropropene has been found to react smoothly with a variety of carbonyl compounds in an aqueous solvent system to give the corresponding 3-chlorohomoallyl alcohols in excellent yields.
