  (−)-Daucic acid: Proof of d-lyxo configuration, synthesis of its d-ribo, d-xylo, l-arabino and l-lyxo analogs, and biosynthetic implications

  摘要：

  The dimethyl esters of the 2,6-anhydro-3-deoxy-hept-2-enaric acids with D-xylo, D-lyxo, L-arabino, L-lyxo- and D-ribo-configuration were synthesized from D-galactose and D-mannose, respectively, and further characterized by their di-O-acetyl and di-O-benzoyl derivatives. Comparison of their physical data with those of Daucus carota derived products revealed (-)-daucic acid to have D-lyxo-configuration 46 rather than the previously assigned D-xylo stereochemistry 1. Dimethyl daucate 43 could be converted by acid-induced ring contraction and dehydration into naturally occurring (+)-osbeckic acid 47, thereby proving its (S)-configuration. Configurational identity in the pyranoid rings of (-)-daucic acid and KDO, together with available biosynthetic evidence on chelidonic acid 4, a leaf closing factor, suggests a joint, KDO 8-P-based pathway for their biosynthesis in plants.

  Two diacyldaucic acids (1 and 2), an alpha,beta-unsaturated gamma-lactone-type lignan (3) and its derivatives (4-6), and 12 known compounds were isolated from a traditional East Asian vegetable, Oenanthe javanica. The absolute configuration of 1 was validated by obtaining (+)-osbeckic acid through acid hydrolysis. The absolute configurations of 3-5 were determined by comparing their experimental and computed ECD data. The conclusion was supported by applying the phenylglycine methyl ester method to 3. Compound 6 was obtained as an interconverting mixture of isomers in a 3:1 trans-cis ratio. Several water-soluble components (1, 3, and 6) showed concentration-dependent inhibitory effects on antigen-stimulated degranulation in RBL-2H3 cells without producing any direct cytotoxicity against RBL-2H3 or HeLa cells.
