Abstract An efficient synthesis of β-alkoxycarbonyl vinylsulfonium salts had been developed. Their reaction with indene-1,3-diones and other activemethylenecompounds provided cyclopropane carboxylates in good yields. A tentative reaction mechanism was proposed.
M-1 cm-1. Fluorine substitution downshifts the LUMO energy level, red-shifts the absorption spectrum, and enhances electron mobility. The polymer solarcells based on the fluorinated electronacceptors exhibit power conversion efficiencies as high as 11.5%, much higher than that of their nonfluorinated counterpart (7.7%). We investigate the effects of the fluorine atom number and position on electronic
2-Nitroindane-1,3-dione derivatives are useful in the prophylaxis and treatment of asthma, hay fever and also in the treatment of rhinitis.
2-硝基茚并-1,3-二酮衍生物在预防和治疗哮喘、花粉热以及鼻炎方面具有用途。
Synthesis of optically active 2-amino-1′-benzyl-2′,5-dioxo-5<i>H</i>-spiro[indeno[1,2-<i>b</i>]pyran-4,3′-indoline]-3-carbonitriles catalyzed by a bifunctional squaramide derived from quinine
The first organocatalytic asymmetric reaction of propylene malononitrile with oxoindole and 1,3-indandione for the synthesis of chiral indeno-spiro compounds has been developed. Under bifunctional squaramide catalysis, a wide range of opticallyactive 5H-spiro[indeno[1,2-b]pyran-4,3′-indoline] derivatives were obtained in excellent yields (up to 95%) with moderate to good enantioselectivities (up to 82%)
已经开发了丙烯丙二腈与氧代吲哚和1,3-茚满二酮的第一有机催化不对称反应,用于合成手性茚并-螺环化合物。在双功能方酰胺催化下,以优异的收率(高达95%)和中等至良好的对映选择性获得了多种旋光的5 H-螺[茚并[1,2 - b ]吡喃-4,3'-二氢吲哚]衍生物(高达82%)。通过大多数产品的简单重结晶过程即可达到90-99%的对映选择性。这些茚并螺化合物是药物发现和生物化学的有希望的候选者。
