Abstract
Synthesis of the N-substituted 1,6-dihydro-3(2H)-pyridinones (3,6 and 9) and 1-acyl-3-piperidones (7 and 10) is described. 1-Benzylpiperidine-3,5-dione (1) was converted into N-substituted 1,6-dihydro-3(2H)-pyridinones (3, 6 and 9) via the methyl enol ethers (2, 5 and 8). Selective reduction of 6 and 9 with Et3SiH in the presence of TiCl4 produced the 1-acyl-3-piperidones (7 and 10).Keywords
