  • Formation of cyclic carbonates in the reactions of 1,2-glycols with oxalyl chloride.
    作者:Taisuke ITAYA、Takehiko IIDA、Hiromi EGUCHI
    DOI:10.1248/cpb.41.408
    日期:——
    Oxalyl chloride reacts with a wide range of 1, 2-glycols in the presence of triethylamine to produce 1, 3-dioxolan-2-ones together with 1, 4-dioxane-2, 3-diones; the ratio of the products largely depends on the structure of the 1, 2-glycol. The formation of the cyclic carbonates may be rationalized in terms of stereoelectronically controlled cleavage of the tetrahedral intermediates.

  • Synthesis of β-hydroxywybutines, the most probable alternatives for the hypermodified base of rat liver phenylalanine transfer ribonucleic acid

    日期:1995.6
    Deoxygenation of the 1,2-glycol (±)-5 was achieved at the position adjacent to the heterocycle through the cyclic carbonate (±)-14, providing the monohydroxy compound 6. This new method of regioselective deoxygenation was employed for the first synthesis of β-hydroxywybutines : oxidation of the methyl butenoate 7 with osmium tetroxide, followed by deoxygenation through the cyclic carbonates (19 and

  • Cyclocondensation of oxalyl chloride with 1,2-glycols
    作者:Takehiko Iida、Taisuke Itaya
    DOI:10.1016/s0040-4020(01)81546-5
    日期:1993.1
    Oxalyl chloride reacts with a wide range of acyclic 1,2-glycols 1 in the presence of triethylamine to produce 1,3-dioxolan-2-ones 3 together with 1,4-dioxane-2,3-diones 2. Ethylene glycol (1d), monosubstituted ethylene glycols 1e, j-1, and erythro-1,2-disubstituted ethylene glycols 1f, m,o provide the cyclic carbonates 3 as the minor products, while the threo-compounds 1g, i, n,p,q and pinacol (1h) afford 3 as the main products. The formation of 3 may be rationalized in terms of stereoelectronically controlled cleavage of the conjugate base 17- of the tetrahedral intermediates. The rate for the conformational change of 17- into 18- and the equilibrium constant between these conformers are proposed to be the major factors affecting the reaction pattern.
