Abstract
BACKGROUND When looking for a safer alternative to pesticides that are potentially harmful to living organisms, one of the directions worth looking at are plant growth-promoting rhizobacteria. The purpose of the research was a comprehensive characterization of Brevibacillus laterosporus K75, a strain isolated from maize rhizosphere. Many studies have proved B. laterosporus to be a biocontrol agent; however, little is known about B. laterosporus as a plant growth-promoting rhizobacterium. RESULTS Ninety strains were screened for plant growth-promoting activities. Four strains with the best plant growth-promoting traits (Rhodococcus qingshengii K8, Bacillus subtilis subsp. stercoris K73, Brevibacillus laterosporus K75, and Brevibacillus laterosporus K89) were used to research their effect on maize growth. Under sterile conditions, B. laterosporus K75 showed the best stimulatory effect, significantly improving the weight of roots, shoots and leaves, and considerably increasing content of chlorophyll. In unsterilized soil, B. laterosporus K75 significantly improved length of roots and weight of leaves compared to the K73, K89, and untreated control. Moreover, B. laterosporus K75 significantly increased specific leaf area compared to the untreated control and to other inoculant treatments. The genome of B. laterosporus K75 was compared to the recently published B. laterosporus MG64. Genome-mining displayed differences in identified plant growth-promoting genes and biosynthetic gene clusters of secondary metabolites. The B. laterosporus K75 genome possessed additional genes involved in indole-3-acetic acid production and phosphate solubilization that could be attributed to its ability to enhance maize growth. CONCLUSION Our study demonstrated that B. laterosporus K75 is a promising candidate for use in inoculant formulation, effectively facilitating maize growth. © 2022 Society of Chemical Industry.

Abstract
The Takai olefination (or Takai reaction) is a method for the conversion of aldehydes to vinyl iodides, and has seen widespread implementation in organic synthesis. The reaction is usually noted for its high (E)-selectivity; however, herein we report the highly (Z)-selective Takai olefination of salicylaldehyde derivatives. Systematic screening of related substrates led to the identification of key factors responsible for this surprising inversion of selectivity, and enabled the development of a modified mechanistic model to rationalise these observations.

Abstract
The enantiodivergent hydroboration reactions of racemic allenylsilane (±)-4 with ( d Ipc)2BH and subsequent crotylboration of achiral aldehydes with the product crotylborane (S)-E-5 at -78 °C provide (E)-δ-silyl-anti-homoallylic alcohols 6 in 71-89% yield and with 93-96% ee. Intriguingly, mismatched double asymmetric crotylboration reactions of enantioenriched chiral aldehydes 20 with (S)-E-5 proceed under Curtin-Hammett control to give anti-3-hydroxylcrotylsilanes 24 as the only products.

Abstract
Kinetically controlled hydroboration of allenylboronate 5 followed by double allylboration with the resulting allylborane (Z)-7 gave (Z)-2-methyl-1,5-anti-pentenediols 6 in good yield and high enantioselectivity in the presence of 10% BF3·OEt2 as the catalyst in the second allylboration step. Under thermodynamically controlled isomerization conditions, (Z)-7 can readily isomerize to (E)-7. Double allylboration of representative aldehydes with allylborane (E)-7 gave (E)-2-methyl-1,5-anti-pentenediols 4 in good yield and high enantioselectivity without requiring use of the BF3·OEt2 catalyst. Thus, 2-methyl-1,5-anti-pentenediols with either olefin geometry can be synthesized from the same allenylboronate precursor 5. Furthermore, 1,5-pentenediols 4 and 6 can be easily converted to 1,3,5-triols with excellent diastereoselectivity in one step.

Abstract
The enantioselective hydroboration of racemic allenylsilane (±)-4 with ((d)Ipc)2BH proceeds via enantiodivergent pathways to give vinylborane 11 and crotylborane intermediate (S)-E-5.
