CONFORMATION AND TAUTOMERIC EQUILIBRIA OF 3-ACYL-3,4-DIHYDROCOUMARINS: A 1H AND 13C NMR STUDY

The steric and electronic effects of acyl substitutents COR (R=Me, i-Pr, Ph and t-Bu) upon conformational and keto-enol equilibria in 3-acyl-3,4-dihydrocoumarins have been studied by 1H and 13C NMR spectroscopy.With the increase of effective size of R, pr

Selective reduction of the endocyclic double bond of 3-substituted coumarins by hantzsch 1,4-dihydropyridine

Hantzsch 1,4-dihydropyridine is a valuable reagent to effect the chemoselective reduction of the 3,4-double bond of 3-substituted coumarins. Georg Thieme Verlag Stuttgart.

Efficient chemoselective reduction of 3-substituted coumarins utilizing ortho-phenylenediamine and benzaldehyde

2-Phenylbenzimidazoline, generated in situ from ortho-phenylenediamine and benzaldehyde, is an effective reagent to achieve the chemoselective reduction of the styrenic double bond in 3-substituted coumarins, which takes place in high yield.
