A reagent controlled organocatalytic enantioselective chlorolactonization reaction has been developed. Several 4-aryl pentenoic acids were cyclized in the presence of 0.1 equiv of (DHQD)2PHAL, employing variousN-chlorinated hydantoins as the terminal chlorenium source. Ten examples are presented with selectivities ranging from 43 to 90%ee. This work represents the first example of an enantioselective reagent-controlled chlorolactonization that approaches synthetically useful enantioselectivities.
