Erythrinin A (10) has been synthesised by the oxidative rearrangement of dihydropyranochalcone 1 with thallium(III) nitrate (TTN) in trimethyl orthoformate (TMOF) to the dimethyl acetal 2, followed by cyclisation to 3, demethylation to 6 and dehydrogenation. Compound 10 could also be obtained from chalcone 4 on similar rearrangement followed by cyclisation, demethoxymethylation and dehydrogenation
通过在原甲酸三甲酯(TMOF)中用硝酸hydro(III)(硝酸盐)将二氢吡喃并二氢萘醌1氧化重排至二甲基乙缩醛2中,然后环化为3,脱甲基化为6和脱氢反应,合成了红霉素A(10)。化合物10也可以通过类似的重排,随后环化,脱甲氧基甲基化和脱氢,从查耳酮4获得。在另一种方法中,查尔酮7在TOF中用TTN氧化重排成8,在用HCl处理时,得到10。
