Chemoselective formation of cyclo-aliphatic and cyclo-olefinic 1,3-diolsviapressure hydrogenation of potentially biobased platform molecules using Kn?lker-type catalysts

The hydrogenative conversions of the biobased platform molecules 4-hydroxycyclopent-2-enone and cyclopentane-1,3-dione to their corresponding 1,3-diols are established using a pre-activated Kn?lker-type iron catalyst. The catalyst exhibits a high selectivity for ketone reduction, and does not induce dehydration. Moreover, by using different substituents of the ligand, thecis-transratio of the products can be affected substantially. A decent compatibility of this catalytic system with various structurally related substrates is demonstrated.

A Method for Synthesis of 3-Hydroxy-1-indanones via Cu-Catalyzed Intramolecular Annulation Reactions

We report a facile and highly efficient method that copper-catalyzed intramolecular annulation to synthesize 3-hydroxy-1-indanones employing simple 2-ethynylbenzaldehyde as starting materials was achieved successfully. This protocol provided a simple synthetic approach to afford 3-hydroxy-1-indanones under mild conditions in good to excellent yields.

Unexpected formation of nitroso-chelated cyclic η1-acylruthenium(II) complex, an effective catalysts for transfer hydrogenation reaction

Reaction of commercial ruthenium complexes M31 and M20 with 2-nitrostyrene gave a new nitroso-chelated cyclic η1-acyl ruthenium(II) complexes Ru-4 and Ru-6 respectively instead of expected Hoveyda-Grubbs type (pre)catalyst Ru-3. New complexes w

Efficient ruthenium-catalyzed transfer hydrogenation/hydrogenation of 1,3-cycloalkanediones to 1,3-cycloalkanediols using microwave heating

A number of 1,3-cycloalkanediones were efficiently reduced to the corresponding diols in good yield by the use of a ruthenium catalyst, 2-propanol, and hydrogen gas under microwave heating.

Facile reduction of aromatic aldehydes, ketones, diketones and oxo aldehydes to alcohols by an aqueous TiCl3/NH3 system: Selectivity and scope

A simple and rapid procedure for the almost quantitative reduction of aromatic aldehydes, ketones, diketones and oxo aldehydes to alcohols by use of TiCl3/NH3 in aqueous methanol solution is reported. The reducing system distinguishes between different classes of aldehydes and/or ketones, and many functionalities that usually do not survive under reducing conditions are tolerated well. The concept of reversal of chemoselectivity has also been developed. A mechanism based on two sequential one-electron transfers from TiIII to the carbonyl carbon atom is proposed, the second SET becoming operative only in the presence of ammonium ion (either added or formed in situ).

2,3-Disubstituted-1-indanones

Compounds of the general formula: SPC1 Wherein m = 0 or 1; Ar is an arylene or lower alkyl substituted arylene radical; R1 and R2, which may be the same or different, are lower alkyl or hydroxyalkyl groups, or EQU1 R3 is H, lower alkyl, benzyl, R4, or EQU2 R4 is SPC2 Alkyl group, an aryl group, EQU3 wherein n=2-6; and R6 is a lower alkyl group or an aryl group. Where m = 1, the formula represents a colorless leuco compound; where m = 0, the formula represents the yellow dye derivative of the leuco. These compounds are particularly useful in photosensitive compositions.
