TL;DR: A three-dimensional covalent organic framework constructed from helical organic threads, designed to be mutually weaving at regular intervals, has been synthesized by imine condensation reactions of aldehyde functionalized copper(I)-bisphenanthroline tetrafluoroborate, Cu(PDB)2(BF4), and benzidine (BZ).
Journal ArticleDOI
Catalyst recognition of cis -1,2-diols enables site-selective functionalization of complex molecules
TL;DR: A catalyst is described that forms a covalent bond to the substrate before selectively functionalizing a proximal functional group and is able to modify the less reactive axial positions within monosaccharides and natural products.
Journal ArticleDOI
Site-Selective Catalysis: Toward a Regiodivergent Resolution of 1,2-Diols
TL;DR: This paper demonstrates that the secondary hydroxyl can be functionalized in preference to the primary hydroxym of a 1,2-diol, using an enantioselective organic catalyst that is able to bond to the diol reversibly and covalently.
Journal ArticleDOI
Scaffolding Catalysts: Highly Enantioselective Desymmetrization Reactions
TL;DR: Ex-changing places: a highly enantioselective desymmetrization of 1,2-diols has been developed in which the catalyst utilizes reversible covalent bonding to the substrate to achieve both high selectivity and rate acceleration.
Journal ArticleDOI
Synthesis of Quaternary Carbon Centers via Hydroformylation
Xixi Sun,K. Frimpong,Kian L. Tan +2 more
TL;DR: The application of hydroformylation to the synthesis of quaternary carbon centers is reported and Ligand 1 serves as a catalytic directing group by covalently and reversibly binding to both the substrate and catalyst.
