- Model Studies on the Effect of Aldehyde Structure on Their Selective Trapping by Phenolic Compounds
-
The reaction among flavor-relevant saturated aldehydes (propanal, 2-methylpropanal, butanal, 2-methylbutanal, 3-methylbutanal, pentanal, hexanal, and glyoxal) and phenolic compounds (resorcinol, 2-methylresorcinol, 2,5-dimethylresorcinol, and orcinol) was

- Unprecedented acetylation of phenols using a catalytic amount of magnesium powder
-
The acetylation of phenols with acetic anhydride was achieved using a catalytic amount of magnesium metal powder under air and solvent-free conditions to afford corresponding phenyl acetates in excellent yield (up to 98%).

- Asymmetric hydrolysis of pro-chiral 3,3-disubstituted 2,4-diacetoxy-cyclohexa-1,4-dienes
-
Asymmetric enzymatic hydrolysis of pro-chiral 3,3-disubstituted 2,4-diacetoxycyclohexa-1,4-dienes 2 affords in high yields optically pure 2,2-disubstituted 3-acetoxycyclohex-3-enones 1 (>98% ee). Under mild conditions Candida cylindracea lipase (enzyme/substrate ratio = 2%) hydrolyses specifically the pro-S enol ester function of the pro-chiral starting material 2.

- Benzodipyrazoles: Non-Xanthine Adenosine Antagonists
-
3,5-Dimethylbenzodipyrazoles, optionally substituted in the 1-, 7-, and 8-positions, were synthesized from resorcinols.These compounds display affinity for adenosine A1 (rat brain) and A2 (human platelet) receptors.In addition, these compounds reverse contractions of guinea pig tracheal cylindrical segments induced by potassium chloride, histamine, acetylcholine, and 5-hydroxytryptamine, as well as reverse bronchospasm induced by aerosolized histamine in the conscious guinea pig.
