The first and efficient syntheses of the naturally occurring prenylated stilbenes chiricanine A (2), arahypin-1 (3), trans-arachidin-2 (4), trans-arachidin-3 (5), and arahypin-5 (6) are described. Syntheses of 2 and 3 were accomplished by either a convergent sequence or a one-step reaction starting from pinosylvin. Syntheses of 4, 5, and 6 were achieved from (E)-3,5-bis-methoxymethyl-4′-triisopropylsilyloxystilbene
天然的异戊烯基斯蒂芬斯鸟氨酸A(2),arahypin-1(3),trans -arachidin-2(4),trans -arachidin-3(5)和arahypin-5(6)的首次合成。描述。2和3的合成是通过聚合序列或从pinosylvin开始的一步反应完成的。的合成4,5和6是从(实现Ë)-3,5-双-甲氧基甲基-4'-三异丙基甲硅烷基氧基sti通过具有双甲氧基甲基醚基的苯甲醛与具有三异丙基甲硅烷基氧基的苄基膦酸酯之间的霍纳-沃兹沃思-埃蒙斯反应获得。
