A Method for the Deprotection of Alkylpinacolyl Boronate Esters
摘要:
A two-step procedure for deprotection of alkylpinacolyl boronate esters via transesterification with diethanolamine followed by hydrolysis was successfully developed with the advantages of tolerance to various functional groups, short reaction time, and ease of product isolation.

development of new strategies to synthesize alkyl arenes is a highly desirable goal, and herein, we present an alternative method to those conventional reactions. Particularly, a simple protocol for the direct C−H alkylation of unbiased arenes with alkylboronic acids in the presence of Mn(OAc)3⋅2H2O is reported. Primary or secondary unactivated alkylboronic acids served as alkylatingagents for the direct
