【文章名】(S)-Pyrrolidin-2-ylmethyl-1,2,3-triazolium salts; ionic liquid supported organocatalysts for enantioselective Michael additions to b-nitrostyrenes.
[摘要]:task-specific ionic liqs. via click reaction and alkylation. They serve as excellent recyclable catalysts in enantioselective Michael addns. to b-nitrostyrenes in excess of carbonyl compds. as reactant and as solvent providing high yields and stereoselectivities.
