Tetrahydropyridazino-1,4-oxazinoisoquinoline derivatives with multidrug resistance (MDR) modulating activity were designed and synthesized. A key step for cyclization of 1,4-oxazine ring was developed using K2CO3 and CH3CN in one-pot. Among prepared compounds, 2-(4-fluorobenzyl)-9,10-dimethoxy-12-methyl-6,7,11b,12-tetrahydropyridazino[4',5',5,6][1,4]oxazine[3,4,-a]isoquinolin-1(2H)-one (If) exhibited significant MDR reversing activity and low toxicity, which might be as potential MDR agent.
