摘要
The organic ligand of the cofactor of the oxomolybdoenzymes has been synthesised in the protected and masked form, 5. The key steps in the conversion of the previously prepared 3, a protected 5-(2-amino-4-oxopteridin-6-yl)-4-(1,2-dihydroxyethyl)-1,3-dithiol-2-one were: formation of the pyran ring by reaction with a chloroformate giving a protected 8-amino-4-hydroxymethyl-6-(alkyloxycarbonyl)-5a,6,9,10-tetrahydro-[1,3]dithiolo[4',5':4,5]pyrano-[3,2-g]pteridine-2,10-dione, 10, cyanoborohydride reduction of the 11,11a-imine, protection at N-11, and finally conversion of the alcohol into a protected phosphate giving 5.
