Effect of Alkyl Substituents on the Hydrogen Catalytic Osmylation of Cis and Trans 2-Cyclohexene-Cyclohexanol
Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3). The steric hindrance of the equatorial OH group probably prevents the trans isomer from entering into such reaction. Triol (3) was also obtained from the reduction of the d...

متن کاملModular synthesis of cyclic cis- and trans-1,2-diamine derivatives.
Structurally diverse carbocycles with two vicinal nitrogen-substituents were prepared in expedient three-component reactions from simple amines, aldehydes, and nitroalkenes. trans,trans-6-Nitrocyclohex-2-enyl amines were obtained in a one-pot domino reaction involving condensation, tautomerisation, conjugate addition, and nitro-Mannich cyclisation. Upon employment of less nucleophilic carboxami...
متن کاملCharacterization and DFT studies of cis, trans and vinyl derivatives of 1,4-butadiene using C20 in different temperatures
In this research of cis, trans and vinyl monomeric derivatives of 1,4-butadiene were studied using C20 in different temperatures by Functional density theory (DFT). To this purpose, the materials were firstly optimized geometrically, then the calculations of the thermodynamic parameters were performed on all of them. In the following, changes in parameters of energy...
متن کاملQuantitative structure - activity relationship study of para - substituted trans - and cis - tamoxifen derivatives
A novel quantitative structure-activity relationship model for para-substituted transand cistamoxifen derivatives is proposed, showing correlation with experimental activities. This model represents an improvement to the reported one.
