Synthesis of a set of isomeric 2,4,6-triarylmorpholines and 2,6-diaryloxathianes from the corresponding 1,5-diols has been described. The method provides an efficient route to six-membered heterocycles from acyclic diols and is found to be better than Mitsunobu procedure in yield and waste management. In a related study, the ring contraction of pyranone to two isomeric cyclopentenone derivatives through Nazarov reaction has been noticed.

Treatment of bis(2-chloro-2-phenylethyl) sulfide, prepared from SCl2 and styrene, with commercially available silica gel in n-hexane and benzene at 30 °C for 6 h gave 2,6-diphenyl-1,4-oxathiane in quantitative yield. The cyclization was success
