An efficient direct asymmetric aldol reaction with zinc triflate and prolinamides as combined catalysts is reported.A series of chiral prolinamides have been designed and used in the direct aldol reaction resulting in the desired products with excellent yields(up to 94% yield) and high enantioselectivities(up to 96% ee).Water was found to play a significant role in the formation of the aldol products,which suggests a new strategy in the design of new organic catalysts.

Electroorganic synthesis is an emerging area of high impact research in organic chemistry, which is considered as one of the green and efficient methods and attracts growing research attention. In this review, we summarized comprehensively the recent literature reports on the electrochemical oxidative difunctionalization of unsaturated C—C bonds. The reaction types described in this review included electrochemical intermolecular cyclization, electrochemical intramolecular cyclization, and electrochemical difunctionalization of alkenes/alkynes. This review focuses on the discussion of its synthetic generality for the preparation of functionalized compounds and the related electrochemical oxidative reaction mechanism.

先天性胫骨假关节(congenital pseudarthrosis of the tibia,CPT)是由于发育异常所致的胫骨畸形,表现为胫骨成角畸形、囊肿或髓腔狭窄等,最终形成不能愈合的假关节。CPT是一种罕见的疾病,其发病率约占新生儿的1/140000~1/250000,主要特点是进行性胫骨和腓骨向前外侧弯曲、病理性骨折、进而发展成胫骨和/或腓骨假关节。该病常与1型神经纤维瘤病(neurofibromatosis type 1,NF_(1))有关,是小儿骨科最难治疗的疾病之一。CPT的病理及发病机制目前尚不完全清楚,存在多种热点研究方向,本文现就病理及发病机制这两方面的研究进展做一综述。
