A practical procedure has been developed for the dynamickineticresolution of 1,2-diarylethanols. This procedure employs a highly enantioselective lipase from Pseudomonas stutzeri (trade name, lipase TL) as the resolutioncatalyst and a rutheniumcomplex as the racemizationcatalyst. Sixteen 1,2-diarylethanols have been efficiently resolved to provide their acetyl derivatives with good yields (95-97%)
Stable ethers are successfully transformed into secondary alcohols via C–O bond activation using a simple cobalt pincer catalyst. Mechanistic studies indicate the involvement of radical pairs, and their sequential recombination and the subsequent hydrolysis results in the formation of secondary alcohols.
Herein, we report a practical and cost-efficient electrochemical method for the highly selective monooxygenation of benzylic C(sp3)−H bonds using continuousflow reactors. The electrochemical method demonstrates excellent scope and scalability by producing 115 g of one of the alcohol products.
