Iridium(III)-Catalyzed C-H Functionalization of Triarylphosphine Oxides with Diazo Dicarbonyl Compounds: Synthesis of α-Aryl 1,3-Dicarbonyl Derivatives

A novel (pentamethylcyclopenta-1,3-dienyl)iridium(III)-catalyzed direct C-H functionalization of triarylphosphine oxides with diazo dicarbonyl compounds through carbene insertion has been developed. This strategy provides a simple and efficient route to t

1-Styryl-3-t-butyl-1,3-propanedione derivative and external preparation for skin using the same

Compounds having excellent UV-A absorptivity and a non-polar oil compatibility, and which can be used topically for treating the skin, are of the formula (R)nPh-CH=CH-CO-CH2-CO-C(CH3)3wherein (R)nPh represents phenyl optionally substituted by up to 3 groups R independently selected from C1 8 alkyl and C1 18 alkoxy.

CONDENSATION OF NITRILES WITH METHYL KETONES AS A METHOD FOR THE SYNTHESIS OF β-AMINOVINYL KETONES

The condensation of nitriles containing aromatic substituents and of trichloroacetonitrile with methyl ketones in the presence of (phenylethylamino)magnesium bromide leads to β-aminovinyl ketones.Acid hydrolysis of the β-aminovinyl ketones gave high yields of the corresponding β-diketones.
