1-氯甲基-4-叔丁基丁二酸

反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A 10 mL vial was charged with a magnetic stirring bar, tert-butyl chloromethyl succinate (24 mg, 0.107 mmol), acetonitrile (2 mL), 3-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-5-morpholino-7H-thieno[3,2-b]pyran-7-one (28) (20 mg, 0.054 mmol) and sodium iodide (12 mg, 0.081 mmol). The reaction mixture was magnetically stirred for 18 hours at 70° C. to give 7-((4-tert-butoxy-4-oxobutanoyloxy)methoxy)-3-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-5-morpholinothieno[3,2-b]pyran-4-ium iodide (81).
