LEWIS ACID MEDIATED SYNTHESIS OF CYCLIC ESTERS

Methods for the synthesis of cyclic phosphonic acid diesters from 1,3-diols are described, whereby cyclic phosphonic acid diesters are produced by reacting a chiral 1,3-diol and an activated phosphonic acid in the presence of a Lewis acid.

Process for preparation of cyclic prodrugs of PMEA and PMPA

The method of preparing compounds of Formula I is described: wherein: M and V are cis to one another and MPO3H2 is a phosphonic acid selected from the group consisting of 9-(2-phosphonylmethoxyethyl)adenine, and (R)-9-(2-phosphonylmethoxypropyl)adenine; wherein V is phenyl, optionally substituted with 1-2 substituents selected from a group consisting of fluoro, chloro, and bromo; comprising: coupling a chiral 1-phenylpropane-1,3-diol, wherein the phenyl may be optionally substituted, with MPOCl2 or an N-6 substituted analogue thereof. Additionally, methods and salt forms are described that enable isolation and purification of the desired isomer.
