DOI: 10.1021/acs.orglett.2c00763
Abstract: Herein, we report a distinctive photoredox/copper dual-catalyzed esterification of benzylic C-H bonds through the combination of photoredox-mediated hydrogen atom transfer and Cu(II)-mediated radical-polar crossover. This methodology demonstrates a high functional group tolerance (>40 examples) and… read more here.

DOI: 10.1021/acs.orglett.5c01854
Abstract: A relay Rh(II)/Pd(0) dual-catalyzed three-component allylic alkylation of alcohols, α-diazo 1,3-diketones, and allyl reagents is successfully developed, which provides a highly chemoselective method for the one-pot synthesis of acyclic α-quaternary allylated β-keto-esters. Remarkably, this transformation… read more here.
