- Syntheses of Aryl Glyoxylate. I. The Reaction of Alkyl Dichloro(alkoxy)acetates with Aromatics in the Presence of Lewis Acid
-
Ethyl dichloro(ethoxy)acetate(1) and methyl dichloro(methoxy)acetate(2) were characterized.The reaction of 1 and 2 with aromatics in the presence of AlCl3 gave a considerable yield of aromatic α-keto ester.The aromatics included mono- and polymethylbenzene and anisol.The reaction was studied under various conditions and the results were compared with the acylation by ethoxalyl or methoxalyl chloride.The reaction mechanism was also discussed.

- SYNTHESIS OF α,β-EPOXY DIAZOMETHYL KETONES
-
The preparation of eighteen epoxy diazomethyl ketones 1 is described.Two general methods were developed.Firstly, treatment of the mixed anhydrides of glycidic acids and carbonic acid ester with diazomethane led to the title compounds in yields ranging from 17-74 percent.Secondly, glycidyl chlorides which were obtained from sodium glycidates and oxalyl chloride, gave the desired products upon treatment with diazomethane ( yields 60-74 percent).The required α,β-epoxy carboxylic esters were prepared by Darzens condensation and epoxidation of α,β-unsaturated esters, but in some cases also by reaction of α-oxo carboxylic esters with diazomethane.
