摘要：

A number of hitherto unreported pyrrolocoumarin derivatives 7a-h, a new tricyclic system, have been synthesised from 6-aminocoumarin 1 by successive tosylation, methylation, detosylation, prop-2-ynylation acid treatment with m-chloroperoxybenzoic acid. Compounds 7a-h have been converted into methoxy derivatives 8a-h by simple treatment with methanol.
