ABSTRACT:
A process for producing cyclic thioether compounds and their synthetic intermediates. The process produces a compound represented by formula (5):wherein G1is an alkylene group, R1is a thiol protecting group, R2is hydrogen or an amino protecting group, and Ar is an aryl group or a 5- to 7-membered heteroaryl group.
