discovered to efficiently stimulate adult rats' neurogenesis. In-depth structure-activity relationship studies proved the necessity of a stilbene scaffold that is absent in highly cytotoxic analogs such as chalcones and heteroaryl rings and inactive analogs such as diphenyl acetylene and diphenyl ethane, and validated the importance of an NH in the carboxamide and a methylenedioxy substituent on the

A decarboxylative coupling reaction for alkynyl carboxylic acids and arylsiloxanes was developed using a palladium catalyst. This method provided the desired coupled products in moderate to good yields by reacting the alkynyl carboxylic acids and arylsiloxanes with Pd(dba)2 (1.0 mol %), 1,1-bis(diphenylphosphino)methane (1.0 mol %), and AgF2 (2.0 equiv) at 60 °C for 6 h.

Cytoprotective compounds, many of which are phenolic derivatives characterized by a substituted phenol having certain conjugated bonds, are useful in the treatment of certain ischemic or inflammatory conditions, including but not limited to stroke, myocardial infarction, congestive heart failure, and skin disorders characterized by inflammation or oxidative damage. They are also useful in the manufacture of pharmaceutical and cosmetic formulations for the treatment of such conditions.

An efficient and general protocol for the deacetonative Sonogashira coupling of aryl propargyl alcohols with aryl chlorides is described. The reaction proceeded smoothly with the catalyst system of palladacycle/Xphos. This result represents the first successful deacetonative Sonogashira version for electron-poor, electron-neutral, and even inactive sterically hindered electron-rich aryl chlorides.
