Selective formation of amides or peptides with ethanol as solvent using a convenient one-pot procedure in which acid activating agent N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDC) is simply added to a mixture of the carboxylic acid, amine, catalytic HOBt (1-hydroxy benzotriazole), and NMM (N-methylmorpholine) as base has been developed. Sensitive functionalities such as hydroxyl groups are well tolerated under the reaction conditions. In addition, isolation of products is usually by simple filtration from the reaction media. The scope and generality of this methodol. was investigated.

Several boron-containing small mols. have been approved by the US FDA to treat human diseases. We explored potential applications of boron-containing compounds in modern agriculture by pursuing multiple research and development programs.

In this report, the C(sp3)-C(sp3) cross-coupling of alcs. and carboxylic acids through the dual combination of N-heterocyclic carbene (NHC)-mediated deoxygenation and hypervalent iodine-mediated decarboxylation were described. This mild and practical Ni-catalyzed radical-coupling protocol was employed to prepare a wide array of alkyl-alkyl cross-coupled products, including highly congested quaternary carbon centers from the corresponding tertiary alcs. or tertiary carboxylic acids. Synthetic applications of this methodol. to alc. C1-alkylation and formal homologation, as well as to the late-stage functionalization of drugs, natural products, and biomols. were demonstrated.tert-Butyl 4-hydroxypiperidine-1-carboxylate(cas: 109384-19-2Recommanded Product: 109384-19-2) was used in this study.

Zhang, Zhenhua; Gorski, Bartosz; Leonori, Daniele published an article in 2022. The article was titled 《Merging Halogen-Atom Transfer (XAT) and Copper Catalysis for the Modular Suzuki-Miyaura-Type Cross-Coupling of Alkyl Iodides and Organoborons》, and you may find the article in Journal of the American Chemical Society.Application of 109384-19-2 The information in the text is summarized as follows:

A mechanistically distinct approach to achieve Suzuki-Miyaura-type cross-couplings between alkyl iodides and aryl organoborons was reported. This process required a copper catalyst but, in contrast with previous approaches based on palladium and nickel systems, does not utilizes the metal for the activation of the alkyl electrophile. Instead, this strategy exploited the halogen-atom transfer ability of α-aminoalkyl radicals to convert secondary alkyl iodides into the corresponding alkyl radicals that then were coupled with aryl, vinyl, alkynyl, benzyl and allyl boronate species. These novel coupling reactions feature simple set up and conditions (1 h at room temperature) and facilitate access to privileged motifs targeted by the pharmaceutical sector. In addition to this study using tert-Butyl 4-hydroxypiperidine-1-carboxylate, there are many other studies that have used tert-Butyl 4-hydroxypiperidine-1-carboxylate(cas: 109384-19-2Application of 109384-19-2) was used in this study.

Kang, Zhenghui; Chang, Wenju; Tian, Xue; Fu, Xiang; Zhao, Wenxuan; Xu, Xinfang; Liang, Yong; Hu, Wenhao published their research in Journal of the American Chemical Society in 2021. The article was titled 《Ternary Catalysis Enabled Three-Component Asymmetric Allylic Alkylation as a Concise Track to Chiral α,α-Disubstituted Ketones》.Formula: C10H19NO3 The article contains the following contents:

Herein, a three-component asym. allylation of α-diazo carbonyl compounds with alcs. and allyl carbonates was disclosed by employing a ternary cooperative catalysis of achiral Pd-complex, Rh2(OAc)4, and chiral phosphoric acid CPA. This method represents the first example of three-component asym. allylic alkylation through an SN1-type trapping process, which involves a convergent assembly of two active intermediates, Pd-allyl species and enol derived from onium ylides, providing an expeditious access to chiral α,α-disubstituted ketones in good to high yields with high to excellent enantioselectivity. Combined exptl. and computational studies have shed light on the mechanism of this novel three-component reaction, including the critical role of Xantphos ligand and the origin of enantioselectivity.
