reaction of ammonia, glyoxal hydrate, and cyclohexanone. It is a very useful precursor for the diastereocontrolled synthesis of many C2-symmetric 1,2-diamines, a class which is important for the generation of a variety of C2-symmetric reagents and catalysts for enantioselective synthesis.
通过氨,乙二醛水合物和环己酮的反应,可以高效,简单地制备出以前未知的5-螺环己基异咪唑。对于许多C 2对称的1,2-二胺的非对映控制合成而言,它是非常有用的前体,这一类对于产生各种C 2对称的试剂和对映选择性合成的催化剂很重要。
