facilitating meta photocycloaddition reactions between phenol and allyl alcohol derivatives has been investigated. The merits of silicon, carbonate and methylene acetal tethers were assessed, whilst considering strategies for the preparation of the natural products gymnomitrol and gelsemine. The photoadducts were epoxidised, and then subjected to acid catalysed fragmentation with concomitant cleavage of the
已经研究了临时系链在促进苯酚和烯丙醇衍生物之间的间位光环加成反应中的用途。评估了硅,碳酸盐和亚甲基缩醛系链的优缺点,同时考虑了制备天然产物裸草胺和明胶的策略。将该光加合物环氧化,然后进行酸催化的断裂,并同时断开系链。取决于在亚甲基系链的断裂阶段中使用的是水还是甲醇,亚甲基被完全除去或转化成MOM基团。
