Transition-metal-free polycyclic indoline formation via a free radical pathway: a computational mechanistic study

The mechanism of [2 + 2 + 1] cyclization reactions to access polycyclic sulfonyl indolines via Fe(II)-catalyzed or UV-driven has been investigated by density functional theory (DFT) methods. Mechanistic studies aided by the DFT calculations suggest that the reaction might proceed via a free radical pathway with HSO3 center dot serving as the initiator and terminator of the free radical reaction, which has never been reported to our knowledge. The reactions involve the formation of two five-membered rings. The calculated results show that the first five-membered ring formation is the rate-determining step, with an energy barrier of 3.2 kcal/mol. And the second five-membered ring formation is an exergonic process. It is worth noting that HSO3 center dot radicals are involved in the reaction preceding the formation of the second ring, and they facilitate formation of the second ring. Meanwhile, the most active site was predicted by the condensed Fukui function (CFF) and verified by DFT calculations.

Computational Design of Enhanced Enantioselectivity in Chiral Phosphoric Acid-Catalyzed Oxidative Desymmetrization of 1,3-Diol Acetals

A general method for the highly enantioselective desymmetrization of 2-alkyl-substituted 1,3-diols is presented. A combination of computational and experimental studies has been utilized to understand the origin of the stereocontrol of oxidative desymmetrization of 1,3-diol benzylideneacetals. DFT calculations demonstrate that the acetal protecting group is highly influential for high enantioselectivity, and a simple but effective new protecting group has been designed. The desymmetrization reactions proceed with high enantioselectivity for a variety of substrates. Moreover, the reaction conditions are also shown to be effective for desymmetrization of 2,2-dialkyl-substituted 1,3-diols, which provides chiral products bearing acyclic all-carbon quaternary stereocenters. The method has been applied to the formal synthesis of indoline alkaloids.

Recent Advances in Metal-catalyzed Alkylation, Alkenylation and Alkynylation of Indole/indoline Benzenoid Nucleus

Selective editing of the benzenoid C-H bonds (C4-C7) in indoles/indolines has received great interest because functionalized indoles/indolines are featured in many marketed drugs and natural products. Transition-metal-catalyzed directed C-H functionalization has thus been developed to manipulate the benzenoid core through C-C and C-heteroatom bond formation. This review covers the recent advances in selective C-C bond forming reactions, alkylation, alkenylation and alkynylation, over the benzenoid ring (C4-C7) of indoles/indolines using metal catalysis.

The inhibition profiles of 4′-acylpyrrole-5-fluoroindolin-2-ones with a C-3′ side chain for VEGFR2, PDGFR-beta, and FGFR-1 protein kinases

In this study, we reported the inhibition profiles of 4 ‘-acylpyrrole-5-fluoroindolin-2-one 3 with a C-3 ‘ side chain for VEGFR2, PDGFR-beta, and FGFR-1 protein kinases. The pyrrole-fused cyclohexanone moiety provided 3 with the best potency to inhibit the three kinases, and the C-3 ‘ side chains contributed to the different inhibition profiles of 3. Compound 3b with a C-3 ‘ 2-carboxylethyl side chain showed good potency for the three kinase (IC50: 25-260 nM), and compound 3g with a N,N-dialkyl-2-carbamoylethyl side chain was more active for VEGFR2 (IC50: 59 nM) and PDGFR-beta (IC50: 16 nM) than FGFR-1 (IC50: 1.7 mu M). The C-3 ‘ 3-(dialkylamino)propyl side chain accomplished 3h-j as selective PDGFR-beta inhibitors (IC50: 7.8-13 nM). Compound 3b was further investigated and found potent to inhibit VEGF- and FGF-dependent cell proliferation with moderate in vivo anticancer activity. Results from docking simulations revealed that the interactions of 3b with VEGFR2 and FGFR-1 which could account for the different inhibition profiles of 3.

Photochromic Cotton Fabric Prepared by Spiropyran-ternimated Water Polyurethane Coating

Photochromic materials have drawn growing interesting due to their capability of interconversion under the action of external optical stimulation, allowing diverse potential applications. Herein, we proposed a novel method of preparing photochromic cotton fabric coated by combined l-(2-hydroxyethyl)-3,3-dimethyl-6-nitrospiro [l(2H)-benzopyran-2,2-indoline] terminated waterborne polyurethane. The synthesized photochromic compounds 1-(2-hydroxyethyl)-3,3-dimethyl-6-nitrospiro[1(2H)-benzopyran-2,2-indoline] (SP-OH), were characterized by FTIR spectra, H-1 NMR and ultraviolet (UV) spectrum. The as-prepared spiropyran-terminated water polyurethane (SP-OH/WPU) was characterized via FTIR spectra, ultraviolet (UV) spectrum, SEM and size analysis. The photochromic cotton fabric was featured via FTIR spectra, ultraviolet (UV) spectrum and SEM. In addition, the photochromic properties, thermal stability of as-prepared cotton fabric was tested. The results showed that the photochromic compounds and SP-OH/WPU have been successfully synthesized and the resultant cotton fabric possesses excellent and durable photochromic properties, including noticeable and quick color alteration under UV radiation and fast recovery when exposed to green light. Furthermore, the excellent thermal stability ensured it undergo harsh service environment, which indicated that it is a good candidate for photochromic textile.
