A practical asymmetricsynthesis of a novel aminopiperidine-fused imidazopyridine dipeptidyl peptidase IV (DPP-4) inhibitor 1 has been developed. Application of a unique three-component cascade coupling with chiral nitro diester 7, which is easily accessed via a highly enantioselective Michaeladdition of dimethyl malonate to a nitrostyrene, allows for the assembly of the functionalized piperidinone
