A chiral metal-organic framework (CMOF) with open chiral channels and multiple recognition sites is constructed from camphoric acid and dipyridyl ligand. It can act as an efficient chiral solid adsorbent,...
Group I−V−VI2 nanocrystals have been considered as potential candidates in the field of optoelectronics owing to their highly tunable semiconductor characteristics. AgSbTe2, one of the emerging Group I−V−VI2 nanocrystals with...
An asymmetric double oxidative [3 + 2] cycloaddition is reported. Oxidation of 3-((2,2,2-trifluoroethyl)amino)indolin-2-ones and β-aryl-substituted aldehydes simultaneously and subsequent asymmetric cycloaddition in the presence of the chiral amino catalyst generated highly functionalized chiral CF 3 -containing spiro[pyrrolidin-3,2′-oxindole] with four contiguous stereocenters stereoselectively, which is characterized by directly constructing two C−C bonds from four C(sp 3 )−H bonds. This new method features mild conditions, broad substrate scope, and excellent functional group compatibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
