  Preparation and Optical Resolution of a New Helical Lactone Carrying the 2,8-Dioxabicyclo[3.3.0]octane Ring System

  摘要：

  A new overcrowded lactone (3) carrying the 2,8-dioxabicyclo [3.3.0] octane ring system was prepared by a simple treatment of tetraol (1) (prepared from 2,7-dihydroxynaphthalene and glyoxal) with 3,5-xylenol, and readily resolved into its enantiomers having a specific rotation of >800degrees (absolute value). A preliminary experiment demonstrated that 3 would be a promising resolving agent.

  Aromatic Compounds with a 3a,6a-Dihydrofuro[2,3-b]furan Moiety. 2. Alkylation Products of Dihydroxynaphthalenes with 1,2-Dihydronaphtho[2,3-b]furan-1,2-diol and Their Structure Analyses

  摘要：

  The alkylation of 2,3-, 2,6-, and 2,7-dihydroxynaphthalenes (DHN) with 1,2-dihydronaphtho[2,1-b]furan-1,2-diol (1) in an acidic condition gave various products derived from 7a,14c-dihydronaphtho[2,1-b]naphtho[1',2':4,5]furo[3,2-d]furan (2a). The products were characterized mainly by NMR spectroscopy with the help of the MNDO MO method. The reaction proceeds via two steps. The hydroxyl group-substituted 2a first formed depending on the starting DHN. These 2a derivatives reacted with another mole of 1 to give the corresponding products with two 3a,6a-dihydrofuro[2,3-b]furan moieties. The product from 2,7-DHN, however, formed in a poor yield, accompanying an unexpected 2a derivative, due to a severe steric hindrance. Another method to prepare these compounds was examined using new precursors with four hydroxyl groups, corresponding to 1.

  10‐tetrahydronaphtho[2,1‐b:7,8‐b′]difuran‐1,2,9,10‐tetraol were transformed into the corresponding isopropylidene derivatives, which were studied mainly by 1H NMR and chiral HPLC analyses in terms of a possible transformation mechanism and stereochemistry in comparison with their corresponding acetyl derivatives.
