Synthesis of (2Z,7Z)-4-(5-bromo-2-(2-(2-(4-bromo-2-((2E)-3-(tert-butylamino)-2,7-bis(tert-butylimino)-5-axo-5,7-dihydro -2H-furo[3,4-b] pyran-4-yl) phenoxy)ethoxy)ethoxy) phenyl)-3-(tert-butylamino)-2H-furo[3,4-b]pyran-5(7H)-one Via four-component reaction

A four-component (3+1) reaction of tert-buthylisocyanide with (6,6 E)-5,5 -(((oxybis(ethane-2,1diyl))bis(oxy))bis(2,1-phenylene))bis(6-(tert-buthylimino)-2,2-dimehyl-5,6-dihydro-4-H-furo[2,3-d][1,3]dioxin-4-one) in CH2Cl2 at room temperature produce new imino-furopyranone based ether groups. The structure of this product is conformed from its IR, 1H NMR, and 13C NMR spectra
