The known photoaddition-fragmentation product (I) was brominated with N-bromosuccinimide in the presence of AIBN to afford bromoester (II), which upon treatment with LiCl in refluxing DMF produced the unsaturated ester (III) with concomitant removal of the methyl carbonate. Subsequent mesylation of the hydroxyl group of (III), followed by elimination with DBU in boiling benzene led to the formation of the diene ester (IV). Selective epoxidation of (IV) with m-chloroperbenzoic acid yielded the epoxy-unsaturated ester (V), which was oxidized with OsO4 and N-methylmorpholine-N-oxide to the epoxy diol (VI). Reaction of (VI) with camphorsulfonic acid in wet CH2Cl2 gave the corresponding tetraol, which on exposure to p-anisaldehyde dimethyl acetal (VII) produced selectively the acetal (VIII). The reduction of the ester group of (VIII) with LiAlH4, followed by silylation with TBDPSi-Cl afforded the monosilylated compound (IX). The reaction of (IX) with SOCl2 in the presence of pyridine generated the cyclic sulfite ester (X), which was oxidized to sulfate (XI) using RuCl3 and NaIO4.
