Dioxolane type 3,4-benzylidene acetals of benzyl β-l-arabinose either as a mixture or pure exo- and endo-isomers cleavaged with BF3· OEt2/Et3SiH in dichloromethane or acetonitrile regioselectively, provided the 4-O-benzyl-

Enantiospecific synthesis of both enantiomers of 2-benzyloxydihydropyran-3- ones from arabinose

Approaches to the enantioselective synthesis of the useful building blocks (2R)- and (2S)-2-benzyloxy-2(H)-pyran-3(6H)-one (12 and 17, respectively) are described. The most direct and highly yielding route for the synthesis of 12 was based on the 'one-pot
