title: An efficient approach to 3,4-disubstituted pyridin-2-ones. Formal synthesis of mappicine ketone.
abstract: Treatment of 3,4-dihydro-3-tosylpyridin-2-one 5 with sodium hydride and then alkyl halides gave various 3,4-disubstituted pyridin-2-ones 6. Formal synthesis of mappicine ketone (1) was also reported.
