A highly efficient protocol for the synthesis of diverse aryl (heteroaryl) substituted pyridyl oxadiazol‐2(3H)‐one analogues using Suzuki‐Miyaura cross‐coupling strategy under microwave enhanced conditions is developed. The method is found to be compatible with a wide range of aryl (heteroaryl) boronic acids.
The title compound dihydro-pyridine was synthesized and structure is established by FT-IR, 1 H NMR, and 13 C NMR spectral analysis. The SC-XRD analysis has been carried out for the determination of molecular structure and its disclosed that crystal relates to monoclinic crystal phase, P21/n1 space group and cell parameters are a= 10.2314(2), b = 7.5215(1), c = 24.5475(4), α = 90, β = 97.921(1)° γ = 90 with 0.34 x 0.33 x 0.30 crystal size. The crystal lattice exhibits inter-molecular H-bonding between N1-H1A-O1. Further inter contacts of the crystal lattice were determined by 3-D Hirshfeld surface (HSA) as well as percentage of contributions have been computed through 2D finger plot depiction. Moreover, bond length, bond angle and torsion angles have been correlated to respective output results of B3LYP/6-311++G(d,p). The electrophilic and nucleophilic characters have been studied through molecular electrostatic potential (MEP) analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
