Palladium/Norbornene Chemistry in the Synthesis of Polycyclic Indolines with Simple Nitrogen Sources

An efficient procedure has been developed to synthesize -indoline derivatives through a palladium-catalyzed Heck reaction/C-H activation/dual amination cascade in one pot. This constitutes the first intermolecular catalytic approach to directly accessN-alkylindolines with a broad substrate scope in the absence of any ligands. This method highlights the use of readily available amines and ureas as the required nitrogen sources in building up the indoline core.

Synthesis and characterization of apHand photoresponsive copolymer of acrylamide and spiropyran

In this research, the solution properties of acrylamide and spiropyran acrylate copolymers were investigated. Spiropyran acrylate was synthesized by the reaction of 1 ‘,3 ‘,3 ‘-trimethyl-6-hydroxyspiro(2H-1-benzopyran-2,2 ‘-indoline) and acryloyl chloride. The free radical solution polymerization was used to attain a specialty responsive polymer. Characterization was carried out using nuclear magnetic resonance (NMR), Fourier-transform spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-vis). The FTIR and NMR results showed that the copolymer synthesis was successful, and the copolymer contained spiropyran monomer. UV analyses indicated that the photoresponsive behavior of the copolymer in the protic and aprotic solvents was quite the opposite, and the polymer absorption spectrum in the basic aqueous solutions was red-shifted.

Preparation and analysis of photochromic behavior of carboxymethyl chitin derivatives containing spiropyran moieties

1MODIFIER LETTER PRIME-(2-Acryloxyethyl)-3,3MODIFIER LETTER PRIME-dimethyl-6-nitrospiro[2 H-1-benzopyran-2,2MODIFIER LETTER PRIME-indoline] (SPA) was synthesized and grafted onto a water-soluble carboxymethyl chitin (CMCH) macromolecule to prepare a photochromic copolymer (CMCH-g-SPA). The structure of CMCH-g-SPA was characterized by Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric (TG) analysis, X-ray diffraction (XRD) analysis, water-solubility evaluation, and UV-vis spectroscopy. XRD patterns of CMCH-g-SPA revealed that grafting copolymerization disrupts the CMCH semicrystalline structure, thus improving water solubility. UV-vis spectroscopy results supported the negative photochromic behavior of the merocyanine (MC) form of CMCH-g-SPA (CMCH-g-MCA) present in a water solution of the target copolymer. In addition to high solvent polarity, the intermolecular and intramolecular electrostatic attraction between the indolenine cation and the COO(-)anion were found to be influencing factors, which stabilize these MC form of spiropyran groups grafted onto CMCH. In a water solution, visible light bleaching was completed over a short period (8 minutes) under artificial visible light irradiation and the thermal coloration reaction, whose rate constant at 25 degrees C was 4.64 x 10(-4) s(-1), which fit the first-order reaction equation. After ten photochromic cycles in water solution, the relative absorption intensity of CMCH-g-MCA decreased by 7.92%.

Replacement of the Hetarene Moiety of Molecule in the Synthesis of Indoline Spiropyran with Cationic Fragment

The paper describes the preparation of a new salt spiropyran of indoline series containing vinyl-3H-indolium fragment in the 8′ position of the 2H-chromene moiety and a chlorine atom in the benzene ring of the indoline fragment. The structure of the reaction product was studied by IR,H-1, and(13)C NMR spectroscopy. The data of X-ray diffraction study indicate that the reaction leads to the partial exchange of the indoline hetarene fragment to provide previously described salt spiropyran containing no chlorine atom in the indoline portion of the molecule.

Steering the antitumor drug discovery campaign towards structurally diverse indolines

Indoline framework is often perpended as a privileged heterocycle present in medicinally valuable compounds of natural and synthetic origin. This review article presents the rational approaches/strategies employed for the design of anticancer indolines along with the structure activity relationship and mechanistic insights revealed in the in-vitro and in-vivo assays. The chemist has always been fascinated towards the indoline ring for the construction of antitumor scaffolds owing to its versatility as evidenced by its existence in scaffolds inducing antiproliferative effects via diverse mechanisms. To the delight of medicinal chemist, the applicability of indoline has also been expanded towards the design of dual inhibitors (multitargeting anticancer agents) as well as PROTACS. Overall, it can be concluded that indoline moiety is a magic bullet and the scaffolds containing this ring are foraying towards detailed preclinical and clinical stage investigations by leaps and bounds.

Here is a downstream synthesis route of the compound 603-62-3, HPLC of Formula: C8H4N2O4

Example 1 (best mode):; A solution of NaOH (2.0 mole) having a strength of 1 5% by weight was cooled to a temperature of 25C. Then 1 .0 mole of 3-nitro-phthalimide was added portionwise under stirring. While maintaining the temperature at 25-30C, 1 .2 mole solution of 12% strength sodium hypochlorite was added portionwise. During addition, the pH of the reaction mass was kept at pH 12.0 with aqueous sodium hydroxide with a concentration of of 15% by weight. After stirring for 2 hours, the reaction mass was cooled down to 5-10 C and acidified with 32% hydrochloric acid to a pH value of 1 .8. After stirring for another hour, the reaction mass was filtered with a suction filter. Then the cake was washed with cold water (8-10 C) and dried under vacuum to yield 6-nitro-anthranilic acid in an amount of 88% of theory.
