Atranes as a new generation of biologically active substances

A family of silatrane‐armed triazole‐encapped salicylaldehyde‐derived Schiff bases: Synthesis, spectral analysis, and antimicrobial and quantum chemical evaluation

“…Another impressive fragment considered to replenish the arsenal of antimicrobial agents is the silatrane template which is an intramolecularly coordinated silicon complex with penta‐coordinated trigonal bipyramidal geometry at the silicon atom, a unique tricyclic atrane ring and a trans‐annular dative bond between silicon and nitrogen that leads to hypercoordination in the silatrane resulting in its exceptional chemical and physical properties . Its very broad application in medicine, agriculture and veterinary sciences has contrived it to show even more exciting future endeavors.…”

Schiff bases of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane and its silatranes: Synthesis and characterization

“…[10][11][12][13] These complexes * For correspondence are valuable for theoretical as well as experimental chemists, as the steric and electronic factors of the silatranes can be adjusted systematically by introducing suitable substituents to bring about subtle structural variations. [14][15][16] Prompted by these recent studies, we have worked on the modification at axial position of silatranes with various derivatives. [17][18][19] In the present work, silatranes 1-5 containing azomethine functional group have been prepared by the reaction between corresponding Schiff base modified silanes of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane and triethanolamine.…”

Role of alkyl silatranes as plant growth regulators: comparative substitution effect on root and shoot development of wheat and maize

“…The presence of the silatrane group sustained the effect or facilitated auxin transport through the biomembranes. It is well known that compounds containing a nitrogen atom in the γ or δ position relative to Si, such as γ‐aminopropyl silatrane, have high physiological activity . Therefore it was of interest to determine whether substitution at the γ position other than the amino group affected the plant growth‐stimulating ability of silatranes.…”

“…It is well known that compounds containing a nitrogen atom in the or position relative to Si, such as -aminopropyl silatrane, have high physiological activity. 7,8 Therefore it was of interest to determine whether substitution at the position other than the amino group affected the plant growth-stimulating ability of silatranes. In this paper, we investigated the seed-germinating ability of different -substituted propyl silatranes and discuss the substitutional effect.…”
