4,6-O-benzylidene

Useful syntheses of D- and L-lyxose from 1,3-O-benzylidene-D- and L-arabinitol have been achieved through the highly selective oxidation of the primary hydroxyl groups by dimethyl sulfoxide-dicyclohexylcarbodiimide.463 Oxidation of but one of the two (equivalent) hydroxyl groups in 1,3,4,6-tetra-O-benzyl-D-mannitol464 and l,6-di-0-benzyl-2,5-0-methylene-D-mannitol465 was possible with dimethyl sulfoxide-acetic anhydride. 

A difference in the behavior of methanesulfonic and p-toluenesul-fonic esters of 1,3-0-benzylidene-tetritols on reduction with lithium aluminum hydride in tetrahydrofuran has been described by Foster and coworkers 1,3-0 -benzylidene -2,4 - di - O - p - tolylsulfonyl - L -erythritol and -L-threitol gave the corresponding 4-deoxytetritol acetals, whereas l,3-0-benzylidene-2,4-di-0-(methylsulfonyl)-L-threitol was simply demethanesulfonylated to 1,3-O-benzylidene-L-threitol.
