Solid-phase synthesis of pyridones and pyridopyrazines as peptidomimetic scaffolds.
Creighton,Zapf,Bu,Goodman
, p. 1407 - 1409 (1999)
[formula: see text] We report the syntheses of peptidomimetic opioids containing the core structure N-alkyl-2-alkyl-2,3-dihydro-4-pyridone. By employing imines bound on a solid support and the Danishefsky diene, this [4 + 2] cyclocondensation reaction fac
