A convenient catalytic method for preparation of new tetrahydropyrido[2,3-d]pyrimidines via a cooperative vinylogous anomeric based oxidation

In this study, a novel functionalized metal–organic frameworks MIL-125(Ti)-N(CH 2 PO 3 H 2 ) 2 was designed and synthesized via post-modification methodology and applicated this catalyst for preparation of new tetrahydropyrido[2,3- d ]pyrimidines.
