A catalytic carboxylation of unactivated primary, secondary, and tertiary alkylchlorides with CO2 at atmospheric pressure is described. This protocol represents the first intermolecular cross-electrophile coupling of unactivatedalkylchlorides, thus leading to new knowledge in the cross-coupling arena.
描述了未活化的伯、仲和叔烷基氯化物在大气压下与 CO2 的催化羧化。该协议代表了未活化烷基氯化物的第一个分子间交叉亲电偶联,从而导致交叉偶联领域的新知识。
Novel Class of Quinone-Bearing Polyamines as Multi-Target-Directed Ligands To Combat Alzheimer's Disease
One of the characteristics of Alzheimer's disease (AD) that hinders the discovery of effective disease-modifying therapies is the multifactorial nature of its etiopathology. To circumvent this drawback, the use of multi-target-directedligands (MTDLs) has recently been proposed as a means of simultaneously hitting several targets involved in the development of the AD syndrome. In this paper, a new
report a cobalt-catalysed enantioselective aza-Barbier reaction of ketimines with various unactivated alkyl halides, including alkyl iodides, alkyl bromides and alkyl chlorides, enabling the formation of chiral α-tertiary aminoesters with a high level of enantioselectivity and excellent functional group tolerance. Primary, secondary and tertiary organoelectrophiles are all tolerated in this asymmetric
