Article Synopsis
  • - A new method has been created for synthesizing indanone derivatives using a palladium-catalyzed reaction with -bromobenzaldehydes and norbornene derivatives.
  • - The process allows for the direct formation of the indanone structure through C-H activation of the aldehyde group, all while using mild reaction conditions.
  • - This innovative approach streamlines the traditional synthesis, making it simpler and more practical for quickly producing indanone compounds.

A concise and highly efficient synthesis method of direct esterification of aldehydes via Pd-catalyzed C-H bond activation of aldehyde group has been developed. The strategy avoids the preoxidation step of aldehyde or use of condensing agents in ester synthesis, which is not only applicable to various alcohols but also suitable for the esterification of phenolics which are usually difficult to be esterified. The methodology has the significant advantages of broad substrate scope, mild reaction conditions, and nonrequirement of additional oxidants.

Photosynthetic bacteria wastewater treatment is an efficient water pollution treatment method, but photosynthetic bacteria fermentation is a multivariable, non-linear, and time-varying process. So it is difficult to establish an accurate model. Aiming at the difficulty of online measurement of key parameters, such as bacterial concentration and matrix concentration in photosynthetic bacteria fermentation process, an improved ant colony algorithm least squares support vector machine (AC-LSSVM) soft sensing model method is proposed in this paper.

Harpertrioate A (), an A,B,D--limonoid with a rearranged ring B incorporating exocyclic C-30, was isolated from the EtOAc extract of twigs. Its structure, including absolute configurations, was determined on the basis of spectroscopic data and X-ray crystallography. This compound exhibited biological activities against Alzheimer's disease by reducing Aβ42 and Aβ40 production and shifting APP processing toward nonamyloidogenic pathway.

Three new diterpenoids () (two abietane type diterpenoids and a paralianone type diterpenoid), together with four known compounds () were isolated from the whole plants of . Their structures were elucidated through spectroscopic analysis and physicochemical characteristics. The cytotoxic activities of compounds against five human tumour cell lines were evaluated, however, they were inactive at the concentration of 40 μM.

Article Synopsis
  • The study aimed to utilize corn stover as animal feed by analyzing its chemical composition and digestibility after field exposure and during fermentation with lactic acid bacteria (LAB) and cellulase.
  • Corn stover was harvested, exposed to natural conditions, and prepared into silage with different treatments over various exposure periods, focusing on its fermentation quality and nutrient content after fermentation.
  • Results indicated that while moisture content and fiber increased, protein and digestibility decreased during field exposure; however, using LAB and cellulase improved fermentation quality and digestibility of the silage compared to the control.

Seven new anthranilamide derivatives, acoapetalines A-G (1-7), including one new naturally occurring compound (7), together with six known ones (8-13) were isolated from the whole plants of Aconitum apetalum. Their structures were established on the basis of extensive spectroscopic analyses (IR, UV, HRESIMS, 1D and 2D NMR). All compounds were evaluated for their anti-tobacco mosaic virus (anti-TMV) activities.

Cytoplasmic male sterility (CMS) is universally utilized in cruciferous vegetables. However, the Chinese cabbage CMS lines, obtained by interspecific hybridization and multiple backcrosses of the () CMS line and Chinese cabbage, show obvious leaf etiolation, and the molecular mechanism of etiolation remains elusive. Here, the ultrastructural and phenotypic features of leaves from the Chinese cabbage CMS line 1409A and maintainer line 1409B are analyzed.
