Synthesis of novel methoxyether derivative of isopulegol in a packed-bed flow reactor
Autor: Upenyu Guyo, Buyiswa G. Hlangothi, Ben Zeelie
Publikováno v: Monatshefte für Chemie - Chemical Monthly. 152:695-704
8–Methoxymenthan–3–ol was synthesised in a packed-bed flow reactor by the reaction of isopulegol and methanol in the presence of amberlyst-15 dry hydrogen form catalyst. Key parameters that affect isopulegol conversion and 8–methoxymenthan–

Isolation and characterisation of altissimin: a novel cytotoxic flavonoid C-apioglucoside from Drimia altissima (Asparagaceae)
Autor: Buyiswa G. Hlangothi, Mutenta N. Nyambe, Denzil R. Beukes, Maryna van de Venter, Bresler Swanepoel
Flavonoids are a class of biologically active compounds with various proven nutraceutical benefits. In flavonoid C-glycosides, the aglycones are attached to sugar residues via cleavage-resistant C-C bonds which alter typical flavonoid pharmacokinetic

Autor: Shanganyane P. Hlangothi, C. D. Woolard, Buyiswa G. Hlangothi
Publikováno v: Plastics, Rubber and Composites. 43:217-224
This paper evaluates the ability of α,ω-alkanedithiols to cross-link high vinyl 3,4-polyisoprene rubber (represented by Isogrip) through the thiol-ene addition reaction and provides microstructural insights into where cross-linking takes place. The
