MELDRUM'S ACID IN ORGANIC SYNTHESIS 4. SYNTHESIS OF 5-SUBSTITUTED 2-PHENYLISOXAZOLIN-3-ONES FROM N-ACYLACETYLPHENYLHYDROXYLAMINES

When N-acylacetylphenylhydroxylamines, readily prepared from phenylhydroxylamine and acyl Meldrum's acids (5-acyl-2,2-dimethyl-1,3-dioxane-4,6-diones) were refluxed in benzene in the presence of a catalytic amount of p-toluenesulfonic acid, an acid-cataly

MELDRUM'S ACID IN ORGANIC SYNTHESIS 3. SYNTHESIS OF 2-SUBSTITUTED INDOLES FROM PHENYLHYDROXYLAMINE

Treatment of phenylhydroxylamine oxalate with acyl Meldrum's acids in boiling acetonitrile readily gave N-acylacetylphenylhydroxylamines, which were converted to 2-substituted indoles by another treatment with acyl Meldrum's acids in refluxing toluene.N-B
