摘要

Reactions of N, N-dimethylformamide and N-methylformanilide with pyrophosphoryl chloride lead to the formation of reagents that undergo reactions with a wide range of nucleophilic aromatic substrates, including indoles, pyrroles, thiophenes, furans, and methoxy- substituted carbocyclic arenes to afford, after hydrolysis of the initial products, good to excellent yields of the expected aldehydes; reactions with methyl oxamates allow the ...
