Notes:
-Nineteen new bimacrocyclic, monomacrocyclic, and nonmacrocyclic pyridines 1-6 bearing amide functions have been synthesized and utilized in base-catalyzed additions of alcohols (ethanol, 2-propanol) and polyols [propane-1,2-diol (11a), butane-1,3-diol (12a), methyl 4,6-O-benzylidene-α-D-glucopyranoside (13a)] to diphenylketene. Compounds 4c, 4d and 1b proved to be efficient and selective catalysts; 4c and 4d exhibited better results with 11a and 12a, and 1b was the best catalyst for selective 2-O-acylation of 13a.
