to react with H2S in vivo to form HNO, thereby activating HNO-TRPA1-CGRP pathway. Inspired by combination therapy, 11 rutaecarpine-furoxan hybrids were designed, synthesized and evaluated. The results demonstrated that most hybrids exerted comparable or improved vasodilator activities. Among which, 13a is the most potent both ex vivo (EC50 = 13.1 nM) and in vivo. Mechanistic studies revealed that the
Disclosed is a practical method for efficiently producing an alcohol compound by hydrogenating an aldehyde by using a homogeneous copper catalyst which is an easily-available low-cost metal species. Specifically disclosed is a method for producing an alcohol compound, which is characterized in that a hydrogenation reaction of an aldehyde compound is performed in the presence of a homogeneous copper catalyst, a monophosphine compound and an alcohol selected from the group consisting of primary alcohols, secondary alcohols and mixtures of those.

The present invention relates to furan derivatives of formula (I), their method of synthesis and uses thereof. Concretely, the compounds disclosed have proved to be inhibitors of glycogen synthase kinase 3β, GSK-3 β, which is known to be involved in different disease and conditions, such as Alzheimer's disease or non-insulin dependent diabetes mellitus. The present invention also relates to pharmaceutical compositions comprising the same. Further, the present invention is directed to the use of the compounds in the manufacture of a medicament for the treatment and/or prevention of a GSK-3 mediated disease or condition.

A Pd-catalyzed method based on the use of a molecular tether is described for olefin difunctionalization. Enabled by an easily introduced trifluoroacetaldehyde-derived tether, a simultaneous introduction of oxygen and nitrogen heteroatoms across unsaturated carbon–carbon bonds was achieved under oxidative conditions, most probably via high-valent Pd intermediates. Good yields and high diastereoselectivity
