Photolysis of the enones 4a–c leads to regioselective hydrogen abstraction and subsequent cyclization to furnish the spiro compounds 5a–d, which on further elaboration provide the spiro dione 6, a model for the antitumour antibiotic, fredericamycin-A 1.
烯酮4a - c的光解会导致区域选择性氢的提取和随后的环化作用,以提供螺化合物5a - d,进一步加工可提供螺二酮6,这是抗肿瘤抗生素弗雷德里卡霉素A 1的模型。
