Synthesis and Characterization of γ-Fe2O3@HAp@β-CD Core-Shell Nanoparticles as a Novel Magnetic Nanoreactor and Its Application in the One-Pot Preparation of β-azido Alcohols, β-nitro Alcohols, and β-cyanohydrins
In this study, β-cyclodextrin(β-CD) supported, hydroxyapatite encapsulated γ-Fe2O3 (γ-Fe2O3@HAp@β-CD) was successfully prepared and evaluated as a solid-liquid phase transfer catalyst and also a molecular host system and nanoreactor for the nucleophilic ring-opening of epoxides in water for the preparation of β-azido alcohols, β-nitro alcohols, an...
متن کاملOrganocatalytic asymmetric Michael-type reaction between β,γ-unsaturated α-keto ester and α-nitro ketone.
A Michael-type reaction of β,γ-unsaturated α-keto ester and α-nitro ketone was established. With a thiourea catalyst derived from cinchona alkaloid, the reactions afford products in 47-94% yields with 68-96% ee.
متن کاملNitro Derivatives of Naturally Occurring β-Asarone and Their Anticancer Activity
β-Asarone (2, 4, 5-trimethoxy-(Z)-1-propenylbenzene) was obtained from Acorus calamus. Nitration of β-asarone with AgNO2/I2 in ether yielded 1-(2, 4, 5-trimethoxy phenyl)-2-nitropropene (1) but with NaNO2/I2 in ethylene glycol obtained 1-(2, 4, 5-trimethoxy phenyl)-1-nitropropene (2). Compound 2 was prepared for the first time and characterized using IR, (1)H-NMR, (13)C-NMR, and GC-MS spectra a...
متن کاملFluorinated β-nitro amines by a selective ZrCl4-catalyzed aza-Henry reaction of (E)-trifluoromethyl aldimines.
ZrCl(4) was found to be an ideal catalyst to promote aza-Henry reactions between trifluoromethyl aldimines and some nitro alkanes giving new fluorinated β-nitro amines. The reaction is strongly influenced by the CF(3) group, the yield by the alkyl chain of the nitro compound, while the stereochemical outcome seems to be unaffected, the anti isomer being always the major product.
متن کامل2-Nitro-N-phenylbenzenesulfonamide
In the title compound, C(12)H(10)N(2)O(4)S, the conformation of the N-H bond in the -SO(2)-NH- fragment is syn to the ortho-nitro group in the sulfonyl-benzene ring. The mol-ecule is twisted at the S-N bond, the C-N-S-C torsion angle being -72.83 (15)°. The dihedral angle between the benzene rings is 59.55 (7)°. The amide H atom and the nitro group O atom form an intra-molecular hydrogen bond, ...
