The chromous chloride promoted addition of N-chlorocarbamates and N- chlorocarboxamides to 1-methoxycyclohexene, ethoxyethylene, dihydropyran, and (1- methoxyethylidene)-cyclohexane gave, in 60 to 85% yields, either α-acyloxy-or α-acylamino ketals and acetals, or the corresponding ketones and aldehydes depending on the work-up conditions. The regio-specificity of the addition was higher with the first two enol ethers (≥ ...
