| Abstract: | The ene-type reaction between silyl enol ethers and azodiesters yields α-keto 4-phenyl 1,2,4 triazolidine-3,5-dione in the case of 1,2,4-triazoline-3,5-dione. and α-keto dicarbo-ethoxyhydrazides in the case of diethyl azodicarboxylate. These reactions proceed in qcod yield and offer potential routes to α-nitrogen substituted ketones. |
