合成路线1
该中间体在本合成路线中的序号：(VI)MK-0826 can be synthesized as follows: The cyclization of 2-diazo-4-[3-(1-hydroxyethyl)-4-oxoazetidin-2-yl]-3-oxopentanoic acid allyl ester (I) by means of rhodium octanoate gives the 2-oxocarbapenam derivative (II), which by reaction with chlorophosphoric acid diphenyl ester (III) and DIEA in acetonitrile yields the enol phosphate (IV). Condensation of (IV) with the sulfanylpyrrolidine (V) by means of DIEA in acetonitrile affords the corresponding addition compound MK-0826 diallyl ester (VI), which is finally deprotected by means of Meldrum's acid and Pd(PPh3)4 in DMF/THF and converted to the sodium salt.
