Abstract :

Novel chiral N-phosphoramide and N-phosphonyl imines were found to be efficient asymmetric chiral auxiliaries. Various nucleophilic addition reactions such as aza-Henry reaction, aza-Darzens reaction, Strecker reaction were performed on these chiral amines and desired products were obtained in excellent chemical yields (94-99%) and diastereo selectivities (upto >99%). These reactions were confirmed to follow the GAP chemistry (group assisted purification chemistry) process, which can avoid traditional chromatography and re-crystallization purifications, i.e., the chiral product bearing a chiral N-‐ phosphonyl group can simply be purified by washing the solid crude products with hexane or hexane:ethylacetate mixture, hence provide a green process to purify organic compounds and motivates the synthetic community to search more of such reagents/processes. Moreover, the chiral auxiliary can be cleaved under acidic conditions and can be easily recovered without loss of chirality.
