It was found that properly protected glycinates (Schiffbase, alkyl/aryl ester) cleanly react with chiral sulfinyl derived phosphoryldifluoro-aldimines at ambient conditions in THF in the presence of catalytic amounts of Cs2CO3. The procedure is operationally simple providing the target addition products with respected (60-80%) yields and excellent (99/1) diastereoselectivity. This approach allows
