A novel approach towards bielschowskysin is reported based on an attempted stepwise cyclobutane formation. Synthesis of the key strained framework, containing the tricyclic ring system and all requisite carbons has been developed. While photochemical studies did not result in a late-stage Norrish–Yang cyclization, the observed isomerization could provide important insights into the synthesis of other
据报道基于尝试的逐步环丁烷形成的一种新的对别尔舒斯基斯基的方法。已开发出包含三环系统和所有必需碳的关键应变骨架的合成。虽然光化学研究并未导致后期的Norrish-Yang环化反应,但观察到的异构化反应可能为其他呋喃类天花类化合物的合成提供重要见解。
