Selective aerobic oxidation of alkyl aromatics on Bi2MoO6 nanoplates decorated with Pt nanoparticles under visible light irradiation

Pt/Bi2MoO6 nanoplates are efficient photocatalysts for the selective oxidation of saturated C-H bonds in alkyl aromatics under visible light illumination using O2 as an oxidant. This study opens a new window for direct C-H functionalization through the photocatalytic method based on cheap Bi2MoO6 semiconductor materials.

COMPOUNDS REDUCING MALODOUR PERCEPTION AND THE USE THEREOF

The present invention relates to new malodour-counteracting agents of formula (I) or stereoisomers thereof, particularly useful in blocking the olfactory perception of androstenone, Formula (I), wherein R1, R2, R3,R4, R5, R6, R7 and X have the same meaning as that defined in the claims. The present invention also relates to consumer products comprising said agents. The present invention also relates to the use of said agents to suppress or attenuate undesirable odour, as well as to methods to suppress or attenuate undesirable odour employing said compounds.

Expeditious construction of a carbobicyclic skeleton via sp3-C-H functionalization: Hydride shift from an aliphatic tertiary position in an internal redox process

Described herein is the first example of an aliphatic, nonbenzylic hydride shift/cyclization sequence that contains two types of novel sp3-C-H functionalization: (1) construction of a tetraline skeleton via [1,5]-hydride shift/cyclization and (2) [1,6]-hydride shift/cyclization to form a five-membered ring (indane derivatives).

5-Benzylidene-1,2-dihydrochromeno[3,4-f]quinolines as selective progesterone receptor modulators

A series of 5-benylidene-1,2-dihydrochromeno[3,4-f]quinolines (4) were synthesized and tested in bioassays to evaluate their progestational activities, receptor- and tissue-selectivity profiles as selective progesterone receptor modulators (SPRMs). Most of the new analogues exhibited as highly potent progestins with more than 100-fold receptor selectivity over other steroid hormone receptors and LG120920 (7b) demonstrated tissue selectivity toward uterus and vagina versus breasts in a rodent model after oral administration.

The undesirable lability of tert-butyldimethylsilyl ethers under Pd/C- catalyzed hydrogenation conditions and solution of the problem by using a Pd/C(en) catalyst

While the frequent and unexpected loss of the TBDMS protective group of a variety of hydroxylic functions was demonstrated under neutral and mild hydrogenation conditions using 10% Pd/C, the undesirable problem was perfectly overcome by using a 10% Pd/C-ethylenediamine complex catalyst.

Electron-transfer-induced reductive cleavage of phthalans: Reactivity and synthetic applications

The behavior of phthalan (1a) was investigated under conditions of electron transfer from alkali metals in aprotic solvents. Reaction with lithium in the presence of a catalytic amount of naphthalene in THF led to the reductive cleavage of an arylmethyl carbon-oxygen bond, with formation of a stable dilithium compound. Trapping of this intermediate with several electrophiles (alkyl halides, carbonyl derivatives, CO2) was successful. The extension of this procedure to several substituted phthalans (1b-i) was investigated, and the regiochemistry as well as the synthetic usefulness of these reactions are discussed.

Reductive electrophilic substitution of phthalans and ring expansion to isochroman derivatives

Reductive cleavage of phthalan, 1a, with Li metal in the presence of a catalytic amount of naphthalene leads to the formation of a stable aromatic dilithium compound. The adducts of the latter with CO2, aldehydes or ketones undergo ring closure to isochroman derivatives, leading to ring expansion of the original heterocycle. The reductive electrophilic substitution procedure was successfully extended to the substituted phthalans 1b and 1c, to afford the corresponding isochroman-3-ones in satisfactory yields.
