Organotransition-metal-modified sugars Part 17. Glucal-derived carbene complexes: syhthesis and diastereoselective benzannulation

10.1016/S0022-328X(00)00748-8

The research focuses on the synthesis and diastereoselective benzannulation of glucal-derived carbene complexes involving organotransition-metal-modified sugars. The study utilizes stannylated precursors 5 and 6 to prepare triisopropylsilyl and isopropylidene-protected 1-lithio-D-glucals, which react with hexacarbonyl chromium and subsequent methylation to yield D-arabino-hex-1-enopyranosylcarbene complexes 7 and 8. These complexes then undergo diastereoselective benzannulation with tolan and 3-hexyne to produce polyoxygenated chromans 9 to 12. The research emphasizes the role of protective groups in controlling the conformation of the glucal moiety in both the carbene ligand and the chroman skeleton. The study employs 1H-NMR studies and single crystal X-ray analyses to determine the conformations of the sugar moiety in solution and solid state, indicating a 5H4-conformation for triisopropylsilyl compounds and a 4H5-conformation for isopropylidene derivatives. The reactions and analyses involve various reagents, protective groups, and spectroscopic techniques, with a particular focus on the stereochemistry and conformational control in the synthesis of these complex organic molecules.
