Hydroformylation, a reaction that installs both a C–H bond and an aldehyde group across an unsaturated substrate, is one of the most important catalytic reactions in both industry and academia. Given the synthetic importance of creating new C–C bonds, the development of carboformylation reactions, wherein a new C–C bond is formed instead of a C–H bond, would bear enormous synthetic potential to rapidly
加氢甲酰化是一种在不饱和底物上同时安装 C-H 键和醛基的反应,是工业界和学术界最重要的催化反应之一。鉴于创造新的 C-C 键的合成重要性,发展碳甲酰化反应,其中形成新的 C-C 键而不是 C-H 键,将具有巨大的合成潜力,可以在有价值的合成中迅速增加分子的复杂性醛类。然而,利用外源 CO 源的四组分反应固有的苛刻复杂性使得直接碳甲酰化反应的发展成为一项艰巨的挑战。在这里,我们描述了一种钯催化策略,该策略使用现成的芳酰氯作为碳亲电试剂和 CO 源,与空间拥挤的氢硅烷串联,进行炔烃的立体选择性碳甲酰化。将该协议扩展到四种化学发散性羰基化,进一步突出了该策略在羰基化化学中提供的创造性机会。

Carbon-linked tetrahydro-pyrazolo-pyridine compounds are described, which are useful as cathepsin S modulators. Such compounds may be used in pharmaceutical compositions and methods for the treatment of disease states, disorders, and conditions mediated by cathepsin S activity, such as psoriasis, pain, multiple sclerosis, atherosclerosis, and rheumatoid arthritis.

achieved by reaction of a porphyrin pentamer + porphyrin monomer or the joining of two porphyrin trimers. In the presence of a tripyridyl template, the yields of the 5 + 1 and 3 + 3 reactions ranged from 10 to 13%. The 5 + 1 reaction in the absence of the template proceeded in 3.5% yield, thereby establishing the structure-directed contribution to cyclic hexamer formation. The 3 + 3 route relied on successive
