Methods for the preparation of esters of 1,4-dihydropyridine-3- and -3,5-carbothiolic acids were developed, and their structure and reactivity were studied. A comparative analysis was made of the spectroscopic characteristics of sulfur-containing esters of the 1,4-dihydropyridine series and their oxygen analogs. More strongly expressed electron-acceptor properties of the COSAlk groupings as compared with alkoxycarbonyl substituents were observed.
