Stereodefined Homopropargyl Amines by Tandem Nucleophilic Addition/Fragmentation of Dihydropyridone Triflates
摘要:
Dihydropyridone (DHPD) triflates undergo nucleophile-triggered fragmentation to provide homopropargyl amine derivatives, the stereochemistry of which is defined by starting from readily available beta-amino esters.
