Highly efficient direct visible-light-mediated oxidative esterification of aldehydes was written by Lindroth, Rickard;Bryce-Rogers, Hogan P.;Merke, Thomas P. M.;Wallentin, Carl-Johan. And the article was included in Photochemical & Photobiological Sciences in 2022.Formula: C10H8O3 This article mentions the following:
A very efficient one-pot procedure for the direct oxidation of aldehydes to esters RC(O)OR1 [R = Ph, cyclohexyl, 4-MeOC6H4, etc.; R1 = Me, Et, t-Bu, etc.] mediated by visible-light was presented. Utilizing a combination of indium triflate and N-bromosuccinimide, NBS, with either ortho-esters or alcs. provided rapid access to a variety of esters RC(O)OR1. Certain substrates convert fully within a few seconds, other more challenging tert-Bu esters RC(O)OR1 [R = 4-PhC6H4; R1 = t-Bu] were formed in good yield after no more than 4 h. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1Formula: C10H8O3).
Methyl benzofuran-2-carboxylate (cas: 1646-27-1) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Formula: C10H8O3
