Subsequently,enol methylation of P in basic condition completed the synthesis of malyngamide O.Applied this route to the synthesis of malyngamides Q and R,the chiral unsaturated acid was connected with the vinyl chloride part by amidation,then the resulting product was converted into the corresponding aldehyde,followed by aldol condensation of the aldehyde with the chlorotitanium enolate of pyrrolidone to complete the skeleton of malyngamides Q and R,then the synthesis of them was completed via enol methylation in acid condition.

该合成路线拓展应用到malyngamides Q和R的合成时,首先用酰胺键将手性不饱和脂肪酸和烯氯片段连接,再转化成相应的醛,与乙酰基吡咯酮进行TiCl_4催化的aldol反应即得到malyngamides Q和R的骨架结构,再经过酸催化的烯醇甲基化反应完成了Q和R的全合成。
