oxidation of acronycine (1) led to keto alcohol 4 which could be reduced to trans-1,2-dihydroxy-1,2-dihydroacronycine (3) using NaBH4. Acylation of 3 afforded 12, 13, and 14. These esters (12, 13, and 14) were more potent than 1 when tested against L-1210 cells in vitro. Diacetate 12 was evaluated in vivo against murine P-388 leukemia and was markedly active at a dose 16-fold lower than acronycine itself.
丙烯醛(1)的
高锰酸盐氧化会生成酮醇4,使用NaBH4可以将其还原为反式
1,2-二羟基-1,2-二氢
丙烯醛(3)。酰化3得到12、13和14。这些酯(12、13和14)在体外针对L-1210细胞测试时比1更有效。在体内评估了
双乙酸酯12对鼠P-388白血病的抵抗力,并且其活性比
丙烯醛本身低16倍。讨论了将这些结果与最近在顺式1,2,2-二羟基-1,2-二氢
丙烯醛系列中获得的结果进行比较。
