The conversion of (-)-2,3-O-isopropylidene-D-erythronolactone (14) and 2-benzyloxy-6-bromo-4-methoxy-3-methyl-aniline (18) into (1R,2R)-(-)-1-azido-2,3,5,8-tetrahydro-7-methoxy-6-methyl-2-methanesulfonyloxy-5,8-dioxo-1H-pyrrolo-[l,2-a]indol-9-yl}methyl phenyl carbonate (39) has been accomplished in 17 steps by way of the enaminone 26. Key steps included the preparation of 26 by a Reformatsky reaction
