BINOL-based foldamers - Access to oligomers with diverse structural architectures

(Chemical Equation Presented) In this article, we report on the synthesis and conformation of a new family of aromatic oligoamide foldamers based on binaphthol (BINOL) monomers. A series of oligomers with differing chirality of the individual BINOL building blocks and mixed sequences of alternate BINOL and pyridyl building blocks has been synthesized and structurally characterized. NMR and quantum chemical calculations on the basis of ab initio MO theory were performed to obtain insight into the conformational features of these oligomers. It is shown that the combination of these inherently chiral aromatic building blocks provides a novel access to a wide variety of conformationally ordered synthetic oligomers with diverse and dazzling structural architectures distinct from those classically observed.

PROCESS FOR POLYMERIZING BETA-BUTYROLACTONE

A process for polymerizing β-butyrolactone is disclosed comprising contacting racemic β-butyrolactone or an enantiomer thereof with a catalyst/initiator system which comprises a rare earth metal, a chiral ligand, at least one nucleophilic ligand, optional

Resolution of (±)-2,2′-dihydroxy-1,1′-binaphthyl-3,3′-dicarboxylic acid using (1R,2R)-trans-cyclohexane-1,2-diamine

A simple and efficient method has been developed to resolve (±)-2,2′-dihydroxy-1,1′-binaphthyl-3,3′-dicarboxylic acid [(±)-BINOL-3,3′-dicarboxylic acid] (±)-1 using inexpensive and readily accessible chiral resolving agent (1R,2R)-trans-cyclohexane-1,2-diamine 2. Enantiomers of BINOL-3,3′-dicarboxylic acid were obtained in good yields and enantiomeric purity, for example, (S)-(-)-1 was isolated in 34% yield with >99% ee and (R)-(+)-1 was obtained in 36% yield with >99% ee. The formation of diastereomeric salt A between (S)-BINOL-3,3′-dicarboxylic acid and (1R,2R)-trans-cyclohexane-1,2-diamine was ascertained by using IR, single crystal X-ray crystallography, and HRMS.

Design and synthesis of two-dimensional pillared MOF layers by connecting infinite one-dimensional chains via 4,4′-bipyridine

Two novel metal-organic frameworks, [Cd(Bna)(DMF)2(H 2O)2] n · nDMF (I) (Bna = 2,2′-dihydroxy-l,l′-dinaphthyl-3,3′-dicarboxylate) and [Cd(Bna)(Bipy)(DMF)2] n (II) (Bipy = 4,4′- bipyridine) have been synthesized under mild conditions and structurally characterized. Crystal structural analyses reveal that complex I adots a 1D spiral structure with DMF guest molecules in the spiral by hydrogen bondings. Complex II is constructed by -Cd-Bna-Cd- zigzag chains, which are further connected by Bipy into a 2D sheet. X-ray powder diffraction and thermogravimetric analyses for I and II show that they are highly themally stable in the solid state.
