Stereodefined homopropargyl amines by tandem nucleophilic addition/fragmentation of dihydropyridone triflates

Tummatorn, Jumreang,Dudley, Gregory B.

supporting information; experimental part, p. 158 - 160 (2011/03/20)

Dihydropyridone (DHPD) triflates undergo nucleophile-triggered fragmentation to provide homopropargyl amine derivatives, the stereochemistry of which is defined by starting from readily available β-amino esters.
