Metalloradical synthesis of medium-sized ring systems, and their applications as molecular photoswitches and synthetic platforms [PDF]
This dissertation is centered around new synthetic applications of metalloradical-carbene-transfer strategies in the synthesis of medium-sized rings, and the utilization of these new cyclic products as molecular photoswitches and synthetic platforms.

Flow system for heterocyclic synthesis [PDF]
The potential of the silver-catalysed cyclisation has been illustrated by the synthesis of furans, pyrroles and pyrazole-N-oxides. With yields predominantly being >95%, and ubiquitous high purity, the results herein show the compatibility of many ...

Analysis of X-ray structure, dielectric properties and AC conductivity of (4E)-2-amino-3-cyanobenzo[b]oxocin-6-one [PDF]
AbstractThe crystal structure of (4E)-2-amino-3-cyanobenzo[b]oxocin-6-one, denoted as 4(E)-ACBO, was analyzed using X-ray diffraction technique. The dielectric and AC electrical conductivity measurements of the bulk 4(E)-ACBO in the form of pellet were studied in the range of frequency 42 Hz to 5 MHz and the temperature range of 303 K to 373 K.

Several aromatase inhibitors have been prepared for treatment of breast cancer; however, the site of interaction with enzyme surface is not very clear. Therefore, the objective of this investigation was to synthesize and analyze the theoretical activity of a new oxocin-steroid derivative against aromatase (2dw3 protein) in a docking model using some ...

Nickel-catalyzed regioselective access to dibenzo[c,f]oxocine framework via reductive Heck reaction
Nickel-catalyzed regioselective construction of dibenzo[c,f]oxocine framework with tri-substituted exo-cyclic alkenes have been obtained through an efficient implementation of reductive-Heck protocol. This cost effective, efficient methodology has been demonstrated for the synthesis of various dibenzo[c,f]oxocine derivatives with moderate to good ...
