Abstract A new set of 5‐bromoindole‐2‐carboxylic acid hydrazone derivatives were synthesized and studied as potential inhibitors VEGFR‐2 tyrosine kinase (TK). Various physical (color, melting point, etc.) spectroscopic (IR, 1 H NMR, 13 C MS) methods used to determine the structure novel 5‐bromoindole derivatives. molecular docking study revealed that 5‐bromo‐N′‐(4‐hydroxy or 4‐chloro 4‐(dimethy...

Aliphatic thiols are in high demand materials chemistry. Herein, a synthesis of thio-derivatives 1-hexene vinylidene dimer is described. The approach, based on hydroalumination reaction with further replacement the organoaluminum function sulfur using thiourea or dimethyl disulfide, provides anti-Markovnikov products, 2-butyloctane-1-thiol 5-(methylsulfanylmethyl)undecane, moderate yields. phos...

the enzymatic hydrolysis of meso-1,7-diacetoxy-2,6-dimethylheptane 5, prepared from 2,6-dimethylhepta-1,6-diene 6, gave the (2s,6r)-7-acetoxy-2,6-dimethyl-1-heptanol 1, which was transformed to the (2r,6r)-2,6,10-trimethyl-1-undecanol 7. in this manner, the c14 side chain of a-tocopherol was synthesized from 2,6-dimethylhepta-1,6-diene 6 in only 5 steps.

The phytotoxic potential of plants and the effect their active components on another plant species is being explored as a alternative to synthetic herbicides for weed control. In current study, we investigated leaves Dregea volubilis (L.f.) Benth. ex Hook.f. against four test [timothy (Phleum pratense L.), barnyard grass (Echinochloa crus-galli (L.) P. Beauv), lettuce (Lactuca sativa alfalfa (M...
