A water-soluble Ru(II)-hm-pheox complex was efficiently catalyzed NH insertion of EDA with a broad class of amine derivatives in water/ether biphasic medium to deliver the biologically active precursors α-aminoester products with excellent yields (up to >99%). The products were separated by decantation and the catalyst was washed and reused several times (at least 8 times) without any specific loss

A group of functionalized b-amino esters were successfully synthesized in excellent yields (> 99 %) via NH-insertion of ethyldiazoacetate into various amines catalyzed by porous-polymer-supported ruthenium(II)-pheox catalyst. The catalyst was readily recovered and reused at least five times without loss of its catalytic activity.
