In an article, published in an article, once mentioned the application of 250285-32-6, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride,molecular formula is C27H37ClN2, is a conventional compound. this article was the specific content is as follows.Quality Control of: 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride
N-heterocyclic carbene-catalyzed all carbon-[4+2] cyclocondensation of alpha,beta-unsaturated acyl chlorides with 3-alkylenyloxindoles
Although the NHC-catalyzed cyclization reactions have been well established for the synthesis of various heterocycles, the corresponding all carbon cyclization reaction for the synthesis of carbocycles is far less established. In this note, the NHC-catalyzed all carbon [4+2] cyclocondensation of alpha,beta-unsaturated acyl chlorides and 3-alkenyloxindoles was developed to give the corresponding spirocarbocyclic oxindoles in good yield with good to high diastereoselectivities. The NHC-catalyzed all carbon [4+2] cyclocondensation of alpha,beta-unsaturated acyl chlorides and 3-alkenyloxindoles was developed to give the corresponding spirocarboncyclic oxindoles in good yield with good to high diastereoselectivities.
