A new and efficient synthetic pathway employed the aldol condensation between the acetophenone (3) and vanillin derivative (4) resulted in the precursor chalcone intermediate (14). The target compound viscolin (1) could be afforded through the hydrogenation of the chalcone and followed by deprotection. The present strategy described the development of a more efficient procedure that allowed large-scale production of viscolin for the further research of biological activity both in vitro and in vivo.
利用苯乙酮(3)和香兰素衍生物(4)之间的醛醇缩合反应生成前体查尔酮中间体(14),这是一种新的高效合成途径。目标化合物 viscolin (1) 可以通过查尔酮的氢化反应和随后的脱保护反应得到。本策略描述了一种更高效程序的开发过程,该程序允许大规模生产粘胶素,以便进一步研究体外和体内的生物活性。
