Abstract
Abstract The novel hydrazone derivatives 2a-c were prepared by treatment of aldehydes 1a, b with some hydrazines. Thiocarbamoyl functional group in compound 2a was subjected to cyclization reactions with some α-halocarbonyl reagents and furnished the novel thiazoles 4- 6, 8 and 9. Enaminonitrile 10 and pyridinone 13 derivatives were synthesized by interaction of active methylene compound 2b with N, N-dimethylformamide-dimethylacetal and ...
