Transformation of epoxides to β-alkoxy alcohols, acetonides, and α-alkoxy ketones is achieved by using molybdenum(VI) dichloride dioxide (MoO2Cl2) as a catalyst. Alcohol, aldehyde, oxime, tosyl, and tert-butyldimethylsilyl functional groups are tolerated during the methanolysis and acetonidation of the functionalized epoxides. No polymerization product is observed with any of the epoxides. Direct conversion of epoxides devoid of sensitive functional groups into the corresponding α-methoxy ketone is achieved in a single step by using the MoO2Cl 2/Oxone system.

LITHIATION OF THE BENZENE RING IN THE PRESENCE OF ortho-ALKYL SUBSTITUENTS BEARING ONE OR TWO HETEROATOMS ON THE β-CARBON. A CONVENIENT SYNTHESIS OF MELLEIN AND KIGELIN

The title reaction can be successfully accomplished by proton-metal exchange with n-butyllithium, and the usually observed elimination to a styrene derivative suppressed, provided an appropriate combination of heteroatoms bound to the β-carbon of the alky
