We have prepared a new chiral nonracemic reagent (5(R)-methyl-1-(chloromethyl)-2-pyrrolidinone) in enantiopure form that reacts with alcohols containing a stereogenic center to produce diastereomeric N-(alkoxymethyl)-2-pyrrolidinone derivatives.These derivatives exhibit large and easily observed diastereotopic signals in the proton NMR that allow direct determination of diastereomeric ratio (percent dr) for the product.
