This paper reports a novel synthesis route to obtain (3S)-16,17-didehydrofalcarinol (1a) in order to provide the quantities necessary for in vivo tests. For this purpose, a two-synthon coupling synthesis was applied. On the one hand, the (Z)-10-bromodeca-1,8-diene (10) was obtained throughout nine steps, and on the other, the hepta-1-en-4,6-diyn-3-ol (11) was obtained in one single step, the fragments
本文报道了一种获得 (3 S )-16,17-二去氢法尔卡林醇 ( 1a ) 的新合成途径,以提供体内试验所需的数量。为此目的,应用了双合成子偶联合成。一方面,通过九步得到( Z )-10-bromodeca-1,8-diene ( 10 ),另一方面,hepta-1-en-4,6-diyn-3-ol ( 11 )在一个单一步骤中获得,片段被偶联得到外消旋1,产率为27%。最后,手性色谱分离1提供了所需的对映异构体1a (27 mg),其针对墨西哥利什曼原虫进行了测试, 证明了其高效的生物活性 (IC 50 = 0.74 μM)。
