  Investigation of Reactive α-Dicarbonyl Compounds Generated from the Maillard Reactions of l-Methionine with Reducing Sugars via Their Stable Quinoxaline Derivatives

  摘要：

  The formation of a-dicarbonyl compounds was investigated in methionine-catalyzed (Mail lard reaction) thermal degradation of D-glucose, maltose, and dextrin 10 at three different pH values (3, 5, and 8). The a-dicarbonyl compounds were trapped as quinoxalines and could be quantified by HPLC and GC-MS. Formation of 1,4-dideoxypentodiulose from hexoses and disaccharides was evidenced for the first time. The use of L-methionine as the amino compound for the formation of 1,4-dideoxypentodiulose in model systems is explained. Furthermore, it could be shown that methionine has great effect on the formation of specific a-dicarbonyl compounds. At various pH values and also by application of mono-, di-, and oligosaccharides in all model reactions, 3-deoxyhexosulose and 1,4-dideoxypentodiulose were generated preferentially.

  A straightforward formal synthesis of the marine natural products laurencione was developed, utilizing elaboration of 5-acetoxy-3-chloropentan-2-one as the starting compound. The synthetic route consisted of (i) α-sulfenylation, (ii) α-chlorination of the resulting β-oxo sulfide, (iii) Hg2+-catalyzed methanolysis, (iv) methanolysis of the γ-acetoxy-α,α-dimethoxy ketone with subsequent cyclization and (v) acid hydrolysis of the acetal. Alternatively, laurencione was prepared from 1,1-dichloroacetone by a sequence of reactions involving (i) imination, (ii) regiospecific β-hydroxyethylation, (iii) hydrolysis, (iv) base-induced rearrangement of the resulting functionalized tetrahydrofuran and (v) final acid hydrolysis of laurencione methyl ether.

• Synthesis of Laurencione, a Labile Dihydro-3(2H)-furanone Derivative from the Red Alga Laurencia spectabilis

  日期：1995.8

  The first total synthesis of laurencione, a naturally occurring dihydro-3(2H-furanone derivative isolated from the red alga Laurencia spectabilis, is described. The synthesis is comprised (1) of conversion of gamma-butyrolactone into alpha,alpha-dimethoxy-gamma-butyrolactone, (2) addition of methyllithium across the lactone carbonyl, and (3) acid hydrolysis of the acetal moiety. An alternative synthesis consists of the acid-catalyzed conversion of 3,3-dimethoxy-2-hydroxy-2-methyltetrahydrofuran into laurencione methyl ether and subsequent acid-catalyzed hydrolysis. In addition, a convenient synthesis of the coffee and caramel flavor component 2-methyl-3(2H)-furanone has been developed by acid-catalyzed rearrangement of 2-methoxy-2-methyltetrahydrofuran-3-one.
