bearing (−)-8-phenylmenthol as a chiral auxiliary with aliphaticaldehydes is realized under photolysis. This work represent the first example of diastereoselective addition of acyl radicals to olefins to afford chiral ketones in a highly stereoselective fashion. The reaction is initiated by the photolysis of hypervalent iodine(III) catalyst under mild and metal-free conditions. The synthetic potential
Diastereoselective radical hydroacylation of chiral alkylidenemalonates with aliphatic aldehydes is realized by the combination of a hypervalentiodine(III) reagent and UV‐light irradiation. The reaction is initiated by the photolysis of hypervalentiodine(III) reagents under mild, metal‐free conditions, and is the first example of diastereoselective addition of acyl radicals to olefins to afford chiral

An enantioselective synthesis of γ-butyrolactones including a formal synthesis of (–)-methylenolactocin 1 is achieved by employing an enantioselective deprotonation of 3-phenylcyclobutanone as a key step.
