Iridium catalysts with chiral P,N ligands have greatly enhanced the scope of asymmetric olefin hydrogenation because they do not require a coordinating group near the C=C bond like Rh and Ru catalysts. Pyridophos ligands, possessing a conformationally restricted annulated pyridine framework linked to a phosphinite group, proved to be particularly effective, inducing high enantioselectivities in the
Reaction of phenylvinylketone with cyclopentanone under thermal conditions resulted in novel domino products, 1,5,9-triketones along with the expected 1,5-diketones. The 1,5,9-triketones were formed via a Michael–Michael-rearrangement pathway. On the other hand, reaction under basic conditions furnished a spiro[4.5]decanone, formed by domino pathways involving Michael–Michael-aldol condensation reactions
苯基乙烯基酮与环戊酮在热条件下的反应产生了新的多米诺骨牌产品1,5,9-三酮以及预期的1,5-二酮。1,5,9-三酮是通过迈克尔-迈克尔重排途径形成的。另一方面,在基本条件下的反应提供了螺[4.5]癸酮,它是由涉及迈克尔-迈克尔-奥尔多缩合反应的多米诺途径形成的。微波介导的1,5,9-三酮的还原胺化-环化反应提供了全氢环戊四[ ij ]喹啉嗪衍生物。
β-(2-Oxocyclopentyl)ethylaryl ketones are transformed under acid conditions via a 2-aryl-bicyclo[3.2.1]oct-2-en-8-one intermediate into a mixture of arylcycloheptene carboxylic acids. The scope and the mechanism of the reaction are both discussed.
