Abstract
A facile access to 2,3-disubstituted-5-ethoxycarbonylpyridines (50-66% yields), derivatives of biologically and medicinally important nicotinic acid, is explored. The method involves the reaction of ethoxycarbonylmalonaldehyde with tosyl chloride and then with β-amino-α,β-unsaturated esters, ketones, or nitriles in the presence of pyridine.
