Reaction of Epoxides with Chlorocarbonylated Compounds Catalyzed by Hexaalkylguanidinium Chloride
摘要:
Silica-supported guanidinium chloride (PBGSiCl) exhibits efficient chemo- and regiospecific catalytic activity in the ring opening of epoxides with various electrophiles. This reaction allows the preparation of beta-chloro esters and beta-chloro chloroformates in high yield-under neutral conditions which offer product stability and ease of product isolation.

A simple and efficientprotocol for palladium-catalyzed C8–H alkoxycarbonylation of 1-naphthylamine derivatives with alkyl chloroformates has been developed, exhibiting broad functional group tolerance, high regioselectivity, and oxidant-free conditions. Furthermore, the reaction features its ease of further functionalization and transformation. For example, the concise synthesis of one BET bromodomain
已经开发了一种简单有效的方案,用于钯催化1-萘胺衍生物与烷基氯甲酸酯的C8–H烷氧基羰基化,具有宽泛的官能团耐受性,高区域选择性和无氧化剂条件。此外,该反应具有易于进一步官能化和转化的特征。例如,从获得的烷氧羰基化产物进行多步转化后,通过苯并[ cd ]吲哚-2(1 H)-1完成了一种BET溴结构域抑制剂的简明合成。另外,对照实验表明,该反应可能涉及自由基过程,而C–H键断裂可能不参与速率确定步骤。

A simple and efficient protocol for silver-promoted direct C–H phosphonation of 1-naphthylamine derivatives with H-phosphonates was described. This reaction proceeded smoothly for 1-naphthylamine derivatives at the C4 site, providing a facile and efficient route to 4-phosphonated 1-naphthylamine derivatives. This phosphonation could tolerate a diverse type of functional groups at the pyridinyl and
