摘要:
A novel process is provided for the preparation of chiral trans-2,3-disubstituted 5-oxotetrahydropyrans of structural formula (I): wherein Ar is optionally substituted phenyl and P is a primary amine protecting group. These compounds are useful in the synthesis of dipeptidyl peptidase-IV inhibitors for the treatment of Type 2 diabetes. Also provided are useful intermediates obtained from the process.
