Abstract
Abstract The title compounds 4 were obtained on treatment of cyanohydrines 3 of aliphatic and aryl aldehydes with oxalyl chloride or bromide in chlorobenzene at 90°C. Evidence for their structure is given by their spectroscopic data and by the Diels Alder reaction of 4 a and 4 g with acetylenic dienophiles to yield substituted pyridines. Cycloaddition was also observed with ethene.
