Studies on Novel and Chiral 1,4-Dihydropyridines. I. Synthesis and Conformational Analysis of Novel NADH Model Compounds, N-Substituted (S)-3-(p-Tolylsulfinyl)-1,4-dihydropyridines.
Preparation of novel NADHmodel compounds, (S)-3-(p-tolyl)sulphinyl-1,4-dihydropyridines and their use in the asymmetricreduction of methyl benzoylformate are described.
Studies on Novel and Chiral 1,4-Dihydropyridines. I. Synthesis and Conformational Analysis of Novel NADH Model Compounds, N-Substituted (S)-3-(p-Tolylsulfinyl)-1,4-dihydropyridines.
Novel NADH model compounds, (SS)-1-alkyl-3-(p-tolylsulfinyl)-1, 4-dihydropyridines (2) and (RS)-1-benzyl-3-[1-oxo-2-(p-tolylsulfinyl)ethyl]-1, 4-dihydropyridine (3), were synthesized. 1H-NMR study and X-ray analysis of 2 revealed its preferred conformation.
