WebThe crucial step of the first methodology was the reaction of (6-chloro-2,4-dimethoxypyrimidin-5-yl)lithium, the nucleobase precursor, with suitable ketones, the carbocyclic pseudosugar precursors. The second approach was based on the copper-catalyzed cross-coupling between magnesiated pyrimidine and appropriate allyl chlorides.
WebThe stereochemistry of the hydrogenation supports our conviction that LAH is functioning as a homogeneous catalyst.16 Usually heterogeneous catalysts promote the hydrogenation of acetylenes predominantly to m-olefins.16 When a long reaction time (10 hr) was required for the hydrogenation of 2-pentyne, the 2-pentene product contained considerable … smoc child care \u0026 head startWebAbstract.
