A green and sustainable visible light-induced triphenylphosphine-promoted deoxygenation strategy to generate acyl radicals from commercially available amino acids has been developed. A wide range of dipeptides, amides and esters were obtained in good yields (77–94%) without epimerization. This strategy has advantages of a short reaction time, no requirement for dry solvents or an inert atmosphere, operationally simple conditions, a broad substrate scope, and good functional group tolerance.

一种可见光介导的脱氧方案，用于合成二肽、酰胺和酯，无需外消旋化


已经开发了一种绿色且可持续的可见光诱导的三苯基膦促进脱氧策略，以从市售氨基酸中生成酰基自由基。以良好的收率 （77-94%） 获得了多种二肽、酰胺和酯，无需差向异构化。该策略具有反应时间短、不需要干燥溶剂或惰性气氛、操作条件简单、底物范围广以及良好的官能团耐受性等优点。
