New 2-R-4-hydroxymethyl-6-methylnikotinates of alkaline metals are synthesized by alkaline hydrolysis of derivatives 6-methyl-1,3-dihydrofuro-[3,4-c]pyridine-3-on
In this article the review about the results of syntheses of new derivatives of pyrasoles,I soxazoles and pyridines, containing furan fragment is given. New methods of the syntheses of material are offered and estimation of their biological activity is made
3-Pyrrol-1-ylthieno[3,2-b]pyridin-2-carboxylic acid[(phenyl, 1,3-benzodioxol-5-yl)methylen]-hydrazides were synthesized by the reaction of
3-pirrol-1-ilthieno[2,3-b]pyridine-2-carbohydra-zides with aromatic aldehydes
To develop the novel herbicide antidotes for the
sunflower vegetative plants, the group of chemical
compounds, belonging to the derivatives of
isoxalopyrazolopyridines was synthesized and their
antidote activity both in the laboratory and field
experiments was studied. The compounds with a high
antidote effect were found
Acylation of amides substituted with pyridine-3-
sulfonic acids oxalil-chlorides and phosgene was
studied. New pyridil-3-sulfonil isocyanates were
synthesized. The conditions for this synthesis were
optimized by taking into account the detailed
understanding of this acylation. The synthesized
pyridine-3-sulfonyl isozyanates were converted to
pyridine-3-sulfonyl ureas. Biological activity of the
new compounds was studied and the substances with
high herbicidal effect were found
In the article we have optimized reaction conditions of furfurilidenatseton with epichlorohydrin in the presence of a catalyst of tin chloride and held hydrogenation of double bond of 2-methylene -2 - [(2-furyl]-X-1,3 – dioxolan; we have also given the
biological activity of some unsaturated furan 1,3- dioxolans
By the method of dipole moments, there has been determined that the tri-coordinated arsenic derivatives (p-XC6H4AsN-R)2 with R= Bu-t in the liquor exist in a cis-form, as for R=С6Н4Х-p the trans-structure is being realized. As for tetra-coordinated derivatives [XC6H4As(S)NBu-t]2 the trans-form is also beeing observed. For ortho-substituted connections, the angles of flat surfaces rotation of benzene rings have been defined
Particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined in the article. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis is analyzed
This publication examines the relationship between the structure of molecules of complexing (descriptors of electronic structure), which are used as inhibitors of hydrogen embrittlement of the steel grade St3, and the content of absorbed hydrogen in model samples-plates made of the above steel. The form of expression of this relationship is the correlation coefficient (CC) by Pearson
Data of the application of researches of vegetative components in reception of drinks from dairy whey of a functional purpose are shown
