Synthesis of oxazolidin-2-ones and imidazolidin-2-ones directly from 1,3-diols or 3-amino alcohols using iodobenzene dichloride and sodium azide
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 iodobenzene dichloride (PhICl2) and sodium azide (NaN3).

Ring opening of cyclic N,O-acetals with allyltrimethylsilane under Lewis acidic conditions
Five and six-membered cyclic N,O-acetals with N-carboxyalkyl and sulfonyl groups undergo clean and high yielding ring opening with allyltrimethylsilane in the presence of strong Lewis acids to give homoallylic amine derivatives.
