A novel and efficient method for the oxidative glycosidation at the heterosubstituted benzylic positions with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) is described. The reaction is stereospecific with 3-substituted isochromans and isothiochroman, a

The use of magnesium metal in methanol for the deprotection of alkyl esters is described. This mild reagent also provides good to excellent selectivity to cleave different esters. The order of the reactivity of this reagent towards acyl cleavages was

3-Carbonyl substituted isothiochromans (3,4-dihydro-1H-2-benzothio- pyrans) (3) were synthesized in moderate yields in a one-pot process from dibromide (1) and 2-mercaptocarbonyl compounds (2). This method could be also extended to the synthesis of t
