Synthesis of perfragilin B, A cytotoxic isoquinoline quinone isolated from the bryozoan Membranipora perfragilis
摘要:
The cytotoxic isoquinoline quinone perfragilin B (2), which was isolated from the bryozoan Membranipora perfragilis, has been synthesized. The key step involves a Diels-Alder reaction between a substituted 2-azabutadiene (4) and 2,3-bis(thiomethyl)-1,4-benzoquinone (6) to produce the isoquinoline skeleton.
