PRODUCTION OF SUBSTITUTED 5,6- AND 3,6-DIHYDRO-2H-PYRANS FROM 4,4-DIMETHYL- AND 4-METHYL-4-PHENYL-1,3-DIOXANES AND CARBONYL COMPOUNDS

2,4-Disubstituted and 2,2,4-trisubstituted dihydropyrans, isomeric with respect to the position of the double bond, were obtained by the reaction of 4,4-dimethyl- and 4-methyl-4-phenyl-1,3-dioxanes with aldehydes and ketones.The effects of temperature and of the amount and nature of the catalyst on the direction and selectivity of the reaction were investigated.
