Abstract: The present invention pertains to the technical field of synthesis and application of novel compounds, and discloses a synthesis method for aryl ethers substituted ortho to nitrogen in nitrogen-containing heterocycles. Under the catalysis of hexamethylphosphoramide (HMPA), using N,N-diisopropylethylamine (DIEA) as a base and with the assistance of POBr3, the method employs nitrogen oxides to react with phenols, thereby achieving ortho-aryloxy substitution on nitrogen heterocycles. The method of the invention exhibits excellent atom economy (3a, 96%), green solvent selection (using ethyl acetate as solvent), mild reaction conditions, short reaction times (most substrates react within 5 minutes), broad substrate scope, and inexpensive and readily available starting materials. This method provides a convenient, efficient, green, and practical approach for synthesizing 1-aryloxyisoquinolines, 2-aryloxyquinolines, and 2-aryloxypyridine compounds.

Abstract: The present disclosure shows a generated, large-scale and realistic patient dataset that mimics real patient data distributions, supports multiple treatments, and provides ground truth for the effects of these treatments. The datasets generated are of synthetic patients modeled on a large nationwide cohort of real patient data including their history of diagnoses, medications, and laboratory values. A data generation process is designed by adapting an Anonymization Through Data Synthesis Using Generative Adversarial Networks (ADS-GAN) model for fictitious patient information generation and using a neural network for treatment outcome generation. The synthetic dataset demonstrates strong similarity to the original dataset as measured by the Wasserstein distance. In addition, privacy of the original patients is preserved so that the dataset can be made available to the research community to evaluate causal inference models.
