Description

General description

cis-2-phenyl-1,3-dioxan-5-ol reacts with triphenylphosphine-carbon tetrabromide to yield cis-4-bromomethyl-2-phenyl-1,3-dioxolan, its trans-diastereoisomer and trans-5-bromo-2-phenyl-1,3-dioxan.

Application

2-Phenyl-1,3-dioxan-5-ol can be used as a starting material in the synthesis of 5-benzyloxy1,3-dioxan-2-one (a carbonate of glycerol monomer). It undergoes ring-opening polymerization with ε-caprolactone in presence of tin(II) 2-ethylhexanoate (Sn(oct)₂).

2-Phenyl-1,3-dioxan-5-ol was used as starting reagent in the synthesis of carbonate of glycerol monomer, 5-benzyloxy-1,3-dioxan-2-one which forms copolymers with ε-caprolactone.
