EXCLUSIVE SOLVENT-CONTROLLED REGIOSELECTIVE CATALYTIC SYNTHESIS OF POTENTIALLY BIOACTIVE IMIDAZOLIDINEIMINODITHIONES: NMR ANALYSIS, COMPUTATIONAL STUDIES AND X-RAY CRYSTAL STRUCTURES

Herein, we describe the first consistent Entry Guards regiospecific reaction of isothiocyanates with a variety of substituted N-arylcyanothioformamides in a 1:1 molar ratio to generate a series of imidazolidineiminodithiones decorated with a multitude of functional groups on both aromatic rings.The reaction is carried out at room temperature using

Electrical Testers Floral symmetry (corolla symmetry) has important biological significance in plant genetics and evolution.However, it is often multi-dimensional and difficult to quantify.Here, we constructed a multi-dimensional data matrix [X Y Z] by extracting three qualitative variables with binary properties (X: corolla regularity of interval

Over the last few years, the role played by corrective feedback in language acquisition has become a highly controversial issue.In the field of First Language Acquisition (FLA), researchers express strong reservations concerning the effect that negative evidence has on FLA, if there is any at all.In the field of Second Language Acquisition (SLA), h

Abstract: BACKGROUND: During pregnancy there is immunological, metabolic, endocrine and vascular changes responsible for physiological and pathological skin changes.OBJECTIVES: determine the prevalence of specific physiological changes and pregnancy, comparing the period of gestation of their appearances and compare type of prenatal care as the ski

IntroductionMedicinal plants are commonly employed mainly due their accessibility, affordability and potency.However, medicinal plants and the associated knowledge are disappearing at an alarming rate due to natural and anthropogenic causes and thus a need for their proper documentation conservation.This study was performed to document traditional
