metabolites, including 3-phenoxybenzoic acid (3-PBA); 3-(2,2-dichlorovinyl)-2,2-dimethylcylopropane carboxylic acid (DCCA); 4-fluoro-3-phenoxybenzoic acid (4F-PBA); and (2,2-dibromovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid (DBCA), depending on the structure of the parent ...
the carboxylic acid moiety was easily converted to libraries of amides51and52. The alcohol moieties of libraries of52could react with CDI and amines to produce libraries of carbamates54. The carboxylic acid and alcohol FGs in library50could react with CDI, followed by treatment with amines to ...
In this paper, we pre-train BERT model based on mask language model on 1.1 million USPTO organic chemical reactions, and the specific structure of the model is shown in Fig. 1b. Pretraining the model with organic reaction data facilitates the acquisition of chemical reaction rules, which are...
The structure of rotenone (Figure 3.3) was established by several research groups simultaneously in 1932 (reviewed by Crombie, 1963; LaForge et al., 1933). Additional notable rotenoids are deguelin, ellipton, malaccol, sumatrol, tephrosin, and α-toxicarol (Crombie, 1963; Fukami a...
Applications of aromatic carboxylic acids in organic synthesis. a The nature choice of aromatic carboxylic acid. b Known ketone synthesis from acids (indirect strategies). c This work: direct deoxygenative C–C coupling by visible light Full size image The concise forging of aryl ketone structural...
Synthesis of 4-carboxyrhodamine dyes In situ formed carboxylic acid salts may be applied to suppress carbonyl group reactivity towards nucleophiles24, but polar carboxylate salts tend to have low solubility in ethereal solvents, which are typically used in lithium–halogen exchange reactions. We prepare...
