Application of a recyclable fluorous oxime in the convenient synthesis of 3-amino-1,2-benzisoxazoles and 4-amino-1H-2,3-benzoxazines

A microwave-assisted, fluorous synthetic route to 3-amino-1,2- benzisoxazoles and 4-amino-1H-2,3-benzoxazines has been developed. The strategy comprises linking the respective 2-fluorobenzonitrile or 2-(bromomethyl) benzonitrile to a fluorous oxime tag to give an aryloxime intermediate which then undergoes cyclization with concomitant cleavage of the substrate-tag in acidic conditions to provide the desired product in good to moderate yields. In addition, the aryloxime intermediate could be subjected to further reactions to expand the compound library. The product could be easily separated using fluorous solid-phase extraction (F-SPE) and the fluorous ketone recovered could be converted back to the fluorous oxime and reused in the next run of the synthesis.

Discovery and lead optimisation of a potent, selective and orally bioavailable RARbeta agonist for the potential treatment of nerve injury

Oxadiazole replacement of an amide linkage in an RARalpha agonist template 1, followed by lead optimisation, has produced a highly potent and selective RARbeta agonist 4-(5-(4,7-dimethylbenzofuran-2-yl)-1,2,4-oxadiazol-3-yl)benzoic acid (10) with good oral bioavailability in the rat and dog. This molecule increases neurite outgrowth in vitro and induces sensory axon regrowth in vivo in a rodent model of avulsion and crush injury, and thus has the potential for the treatment of nerve injury.

Benzisothiazole and benzisoxazole piperazine derivatives

Disubstituted N,N-piperazinyl derivatives are disclosed wherein one substituent is benzisothiazol-3-yl or benzisoxazol-3-yl and the other is alkylene attached to heterocycles such as azaspiro[4.5]decanedione, dialkylglutarimide, thiazolidinedione and spirocyclopentylthiazolidinedione or butyrophenone-like groups. The compounds have psychotropic properties and 8-[4-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]butyl]-8-azaspior[4.5]decane-7,9-dione is a typical embodiment having selective antipsychotic activity.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, 16263-52-8, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 16263-52-8

Photochemistry of 3-amino-1,2-benzisoxazole: unexpected photoisomerization of an amino-spiro-2H-azirine to a 1H-diazirine

UV irradiation of 3-amino-1,2-benzisoxazole isolated in an argon matrix leads to the formation of an amino-spiro-2H-azirine. The amino-spiro-2H-azirine was found to photoisomerize back to 3-amino-1,2-benzisoxazole and also to a 1H-diazirine, which isomerizes to a carbodiimide. All the reported species were characterized experimentally by IR spectroscopy and confirmed by comparison with theoretical IR spectra. The discovery of the transformation of an amino-spiro-2H-azirine into a 1H-diazirine is unprecedented in the chemistry of reactive intermediates.

Synthesis of New Isoxazoles from Isoxazolines, Chalkones, Chalkone Dibromides, Epoxides and Acetylated Ketoximes and Their Conversion into Novel Heterocycles

A convenient and easy conversion of 2-isoxazolines (II) to isoxazoles (V) via N-bromosuccinimide bromination and subsequent dehydrobromination with bases is described.The isoxazoles have also been synthesized from chalkones (I), chalkone dibromides (III) and chalkone epoxides (IV). 1,2-Benzisoxazoles (IX) and naphth<2,1-d>isoxazoles (XIV) have been prepared by the pyrolysis of acetylated ketoximes (VIII and XIII).Methylene-4,4′-bis(3-acylnaphthols) (XVIa-c), prepared by the action of paraformaldehyde on 2-acylnaphthols (XIa-c) in boiling amyl alcohol, are converted into dioximes (XVIIa-c) and then into bis(oxime-acetates) (XVIIIa-c) which on pyrolysis undergo cyclization to give methylene-5,5′-bis(3-alkylnaphth<2,1-d>isoxazoles).Methylene-5,5′-bis(3-methylnaphth<2,1-d>isoxazole (XIXa) on condensation with benzaldehyde and p-anisaldehyde gives the corresponding styryl drivatives (XXa,b).Compounds XIXa-c and XXa,b have also been prepared by the action of paraformaldehyde on 3-alkyl- and 3-styryl-naphth<2,1-d>isoxazoles (XIVa-c and XVa,b) in boiling xylene.The styryl derivatives Xa-d and XVa,b react smoothly with maleic anhydride to give 4-aryl-1,3-dioxo-1,3a,4,1Ob-tetrahydro-2,10-dioxa-10a-aza–3H-cyclopentafluorenes (XXIa-d) and 4-aryl-1,3-dioxo-1,3a,4,12b-tetrahydro-2,12-dioxa-12-aza-3H-cyclopentabenzofluorenes (XXIIIa,b).The fluorenes XXIa and XXIIIa on hydrolysis give 7-hydroxy-3-phenyl-2,3-dihydro-1H-pyrido<1,2-b><1,2>benzisoxazole-1,2-dicarboxylic acid (XXII) and 3-phenyl-2,3-dihydro-1H-pyrido<1,2-b>benzo<1,2>benzisoxazole-1,2-dicarboxylic acid (XXIV), respectively.
