Abstract

Sterically hindered boronic esters of (R,R)-1,2-dicyclohexyl-1,2-ethanediol or pinanediol react with thionyl chloride and excess imidazole in acetonitrile on a borosilicate glass surface (but not on silica or soda-lime glass) to form the corresponding cyclic sulfite of the diol and the ...
