Pyridinethiones. XI. Diastereoselective aldol condensations with 2(1H)‐pyridones, 2(1H)‐pyridinethiones, and the crystal structure of 3‐(1‐hydroxy‐2‐methyl‐3‐oxo‐3‐(4‐chlorophenyl)propyl‐1‐isoprpyl‐2(1H)‐pyridinethione

“…A comparison of the latter structure with the results from the present structure determination reveals some obvious differences. In the structure of ethyl-a-dimethylaminocroconate the substituted pyridine ring exhibits similar variations of the bond lengths [8]. In the structure of ethyl-a-dimethylaminocroconate the substituted pyridine ring exhibits similar variations of the bond lengths [8].…”
