摘要:The present invention relates to the design and synthesis of a class of novel chiral phosphine ligand, 1,2-bis(diphenylphosphinoalkylamido)-1,2-disubstituted ethane, and use in asymmetric catalytic reactions, such as asymmetric catalytic synthesis of pyrazoline-5-one with a chiral quaternary carbon center, i.e., highly enantioselective synthesis of 3-methyl-4-benzyl-4-(2-butyl-2,3-butadienyl)pyrazoline-5-one by using 3-methyl-4-benzylpyrazoline-5-one and benzyl (2-butyl-2,3-butadienyl) carbonate with tris(dibenzylideneacetone)dipalladium-chloroform adduct and this novel ligand as catalysts. The ligand designed by this present invention has the following advantages: the structure is novel, the synthesis and enlarge are simple, the enantioselective control effect in the practical reaction is excellent, which has a broad application prospect in chiral catalysis.

摘要:The disclosure deals with novel synthesis involving (a) hydrogenation of a cis-3,3-dialkyl-3,4-dihydroquinoxaline-2-one in the presence of a suitable hydrogenation catalyst, at elevated temperature and pressure, to yield a cis-3,3-dialkyl decahydroquinoxaline-2-one; (b) reaction of trans-1,2-diaminocyclohexane with acetone cyanohydrin in the presence of water to yield trans-3,3-dimethyl-decahydroquinoxaline-2-one; and (c) a reaction of 1,2-diamine with a saturated acyclic or cyclic monoketone or aldehyde and a holoform, in the presence of (i) a phase transfer catalyst (ii) an organic solvent, and (iii) solid or aqueous alkali to yield 2-keto-1,4-diazacycloalkanes. Such compounds exhibit exceptional UV light stabilizing property.
