Ignatiuk, Zaneta A.; Janicki, Mikolaj J.; Gora, Robert W.; Konieczny, Krzysztof; Kowalczyk, Rafal published the artcile< Applications of Thermal Activation, Ball-milling and Aqueous Medium in Stereoselective Michael Addition of Nitromethane to En-ynones Catalyzed by Chiral Squaramides>, HPLC of Formula: 112-63-0, the main research area is nitromethane enynone chiral squaramide enantioselective regioselective Michael addition; nitromethyl aryl phenyl pentynone.
Stereoselective addition of nitromethane to conjugated en-ynones was performed through the application of chiral squaramides. Three non-classical approaches to promote the addition reaction were tested, including activation of the nucleophile by inorganic base in a biphasic aqueous system, thermal activation, and ball-milling. Hydrogen-bonding catalysis was effective in all these methods, providing 1,4-addition products in high yields and stereoselectivities of up to 98% requiring 1-5 mol% of Cinchona alkaloid squaramide.
Advanced Synthesis & Catalysis published new progress about Alcohols, propargyl Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, HPLC of Formula: 112-63-0.
