The synthesis of the fully functionalized tris-oxazole fragment 9 found in marine metabolites kabiramide C and halichondramide is reported employing modified Hantzsch methodology. Starting with the condensation reaction between cinnamamide 1 and ethyl bromopyruvate 2, the synthetic sequence leading to 9 was carried out in 13 steps with an overall yield of 26%.
据报道,采用改良的Hantzsch方法合成了海洋代谢产物kabiramide C和halichondramide中完全官能化的tris-恶唑片段9。从肉桂酰胺1和溴丙酮酸乙酯2之间的缩合反应开始,导致9的合成序列以13个步骤进行,总收率为26%。
