A general and efficient method for the synthesis of oxazolidin‐2‐ones and imidazolidin‐2‐ones directly from 1,3‐diols and 3‐amino alcohols has been developed using the same reagent combination of iodobenzenedichloride (PhICl2) and sodium azide (NaN3).

An efficient and simple Cu-catalyzed Reformatsky reaction of ketones and aldehydes has been accomplished with ethyl iodoacetate. Excellent yields of β-hydroxyl esters were achieved with a range of ketones and aldehydes, which varied from aromatic to aliphatic, unsaturated to saturated ketones and aldehydes. This practical and convenient transformation was conducted with inexpensive, readily available
