Angular furanocoumarins (1) were synthesized via sequential reactions of vinylation of halo-hydroxycoumarins (5 or 6) with chlorodimethylvinylsilane (8)and Pd catalyst, oxidation of Tl(NO3)3 in methanol, and treatment with acid.
角呋喃香豆素(1)是通过卤代羟基香豆素(5 或 6)与氯二甲基乙烯基硅烷(8)和钯催化剂发生乙烯基化反应、Tl(NO3)3 在甲醇中氧化以及酸处理等连续反应合成的。
