STUDY ON ^(13)C NMR SPECTRA OF SUBSTITUTED 2,6-DIOXABICYCLO[3, 1, 1]HEPTANES: 1,3-ANHYDRO-β-L-RHAMNOPYRANOSE AND-β-D-MANNOPYRANOSE ETHERS

摘　　要：Great attention has been paid to the synthesis and structural analysis of 1, 3-anhydro-pyranose derivatives since B. Samuelsson reported the structure and strong biological activities of Thromboxane A₂（TXA₂） for platelet aggregation, vasoconstriction and contraction of smooth muscle in 1975. The nucleus of 2, 6-dioxabicyclo [3,1,1] heptane has been considered to play an important role in the strong bioactiv ities of TXA₂. It is difficult to investigate the molecular structure of TXA₂
