Abstract

The synthesis, structural characterization, and catalytic application of two novel aluminum complexes, [κ3ENSe−{Ph2P(E)N−C6H4−SePh}AlMe2] [E=S (1) and Se (2)] supported by new pincer‐type phenylselenium‐phosphanamidinate chalcogenide ligands are described. The molecular structures of both complexes in their solid states reveal a distorted trigonal bipyramidal geometry around the Al(III) ion, involving monoanionic ligand {Ph2P(E)N−C6H4−SePh}− bonded to the AlMe2‐motif in a tridentate manner. Complex 1 was found to be an effective pre‐catalyst for the cyanosilyation of aldehydes and ketones with TMSCN under solvent‐free conditions. The reaction protocol is simple, efficient, and has a diverse substrate scope of aldehydes and ketones, showing superior functional group tolerance. The kinetic study revealed that ketone reduction proceeded with first‐order dependence on ketone concentrations, TMSCN, and catalyst 1. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Dendrobine, a valuable alkaloid found in Dendrobium nobile, possesses significant pharmaceutical potential. Methods: In this study, we explored innovative approaches to enhance dendrobine production by utilizing endophytic fungi in a Temporary Immersion Bioreactor System (TIBS, Nanjing BioFunction Co. Ltd., China) and traditional test bottles. Dendrobine was unequivocally identified and characterised in D. nobile co-culture seedlings through UHPLC analysis and LC-MS qTOF analysis, supported by reference standards. Results: The CGTB (control group) and EGTB (experimental group) 12-monthold D. nobile seedlings exhibited similar peak retention times at 7.6±0.1 minutes, with dendrobine identified as C16H25NO2 (molecular weight 264.195). The EGTB, co-cultured with Trichoderma longibrachiatum (MD33), displayed a 2.6-fold dendrobine increase (1804.23 ng/ml) compared to the CGTB (685.95 ng/ml). Furthermore, a bioanalytical approach was applied to investigate the monoculture of T. longibrachiatum MD33 with or without D. nobile seedlings in test bottles. The newly developed UHPLC-MS method allowed for dendrobine identification at a retention time of 7.6±0.1 minutes for control and 7.6±0.1 minutes for co-culture. Additionally, we explored TIBS to enhance dendrobine production. Co-culturing D. nobile seedlings with Trichoderma longibrachiatum (MD33) in the TIBS system led to a substantial 9.7-fold dendrobine increase (4415.77 ng/ml) compared to the control (454.01 ng/ml) after just 7 days. The comparative analysis of dendrobine concentration between EGTB and EGTIBS highlighted the remarkable potential of TIBS for optimizing dendrobine production. Future research may focus on scaling up the TIBS approach for commercial dendrobine production and investigating the underlying mechanisms for enhanced dendrobine biosynthesis in D. nobile. The structural elucidation of dendrobine was achieved through ¹H and 13C NMR spectroscopy, revealing a complex array of proton environments and distinct carbon environments, providing essential insights for the comprehensive characterization of the compound. Discussion: These findings hold promise for pharmaceutical and industrial applications of dendrobine and underline the role of endophytic fungi in enhancing secondary metabolite production in medicinal plants.

43. Role of Bis(phosphinimino)methanides as Universal Ligands in the Coordination Sphere of Metals across the Periodic Table.

Author

Abstract

The coordination chemistry of bis-(phosphinimino)-methanide ligands is widespread and accompanies a large number of metal ions in the periodic table ranging from lithium to neptunium. This unique class of ligand systems show copious coordination chemistry with the main-group, transition, rare-earth, and actinide metals and are considered to be among the most attractive ligand systems to researchers. The bis-(phosphinimino)-methanide metal complexes offer an extensive range of applications in various fields and have been demonstrated as one of the universal ligand systems to stabilize the metal ions in not only their usual but also their unusual oxidation states. The main-group and transition metal chemistry using bis-(phosphinimino)-methanides as ligands was last updated almost a decade ago. In this review, we provide a comprehensive overview of various state-of-the-art bis-(phosphinimino)-methanide-supported metal complexes by dealing with their synthesis, characterization, reactivity, and catalytic studies which were not included in the last critical reviews.

Abstract

A deep eutectic solvent (DES) containing choline chloride (ChCl) and urea (1 : 2) was introduced as an efficient, cost-effective, reusable, and environmentally benign medium for the metal-free synthesis of α-aminophosphine oxide/phosphonate derivatives from one-pot, three-component hydrophosphorylation reactions of aldehydes, amines, and diphenylphosphine oxides/diethylphosphite. Here ChCl–urea (1 : 2) DES played a dual role, namely that of a solvent as well as an efficient catalyst. Using this protocol, diverse α-aminophosphorous derivatives were obtained in excellent yields after short duration, with decent functional group tolerance. [ABSTRACT FROM AUTHOR]
