A series of aminoalkanol derivatives of 10-(diphenylmethylene)-4-azatricyclo[5.2.1.0(2.6)]dec-8-ene-3,5-dione and 4-hydroxy-4-azatricyclo[5.2.1.0(2,6)]dec-8-ene-3,5-dione have been prepared. The pharmacological profile of selected compounds was evaluated for their affinities at beta-adrenoceptors. The investigated compounds exhibit modest affinity for these receptors.

A general approach towards the synthesis of tetrahydro-4-pyrazolo[1,5-][1,4]diazepin-4-one, tetrahydro[1,4]diazepino[1,2-]indol-1-one and tetrahydro-1-benzo[4,5]imidazo[1,2-][1,4]diazepin-1-one derivatives was introduced. A regioselective strategy was developed for synthesizing ethyl 1-(oxiran-2-ylmethyl)-1-pyrazole-5-carboxylates from easily accessible 3(5)-aryl- or methyl-1-pyrazole-5(3)-carboxylates. Obtained intermediates were further treated with amines resulting in oxirane ring-opening and direct cyclisation-yielding target pyrazolo[1,5-][1,4]diazepin-4-ones.

The design and synthesis of functionalized isoindigo compounds by reaction of isoindigo with ()-glycidyl tosylate, epibromohydrin, 2-(bromomethyl)-1-(arylsulfonyl)aziridine, and 2-(bromomethyl)-1-(alkylsulfonyl)aziridine in the presence of MeONa proceed under mild conditions in moderate yields. (3,3')-3,3'-(Ethane-1,2-diylidene)bis(1-(oxiran-2-ylmethyl)indolin-2-one), with an extended central olefin π-conjugated moiety was also reacted with methyl-oxiranes to give the corresponding -disubstituted derivative. Calculations with DFT and TD-DFT of hypothetical isoindigo-thiophene DA molecules with various electron withdrawing substituents, including aziridine, oxirane, nitrile, carbonyl, and sulfonate, indicated that the proximity and strength of the functional group have a significant effect on the HOMO, LUMO, vertical excitation energy, and oscillator strength of the π-π* transitions.

, -Bis(2,3-dihydroxypropyl)-2,4,6-triiodo-5-(-(oxiran-2-ylmethyl)acetamido)isophthalamide (), the alleged precursor of several minor byproducts formed when the X-ray contrast agent iodixanol is synthesized from 5-acetamido- , -bis(2,3-dihydroxypropyl)-2,4,6-triiodoisophthalamide (), has been successfully prepared with an overall yield of 25%. Epoxide enabled the confirmation of its presence in the reaction mixture during the preparation of iodixanol when amide was used as the starting material.

Present study is designed for the synthesis, characterization and corrosion inhibition behavior of two diamine aromatic epoxy pre-polymers (DAEPs) namely, N,N,N,N-tetrakis (oxiran-2-ylmethyl) benzene-1,2-diamine (DAEP1) and 4-methyl-N,N,N,N-tetrakis (oxiran-2-ylmethyl) benzene-1,2-diamine (DAEP2) for carbon steel corrosion in acidic medium. Synthesized DAEPs were characterized using spectral (Nuclear magnetic resonance (H NMR) and Fourier transform infrared-attenuated total reflection (FTIR-ATR)) techniques. Viscosity studies carried out at four different temperatures (20-80 °C) increase in temperature causes significant reduction in their viscosities.
