  自动机器学习辅助 TEMPO 催化伯醇氧化制备羧酸

  摘要：

  尽管醇氧化被认为是成熟的反应，但选择生产条件或预测未见醇的反应产率仍然是主要挑战。在此，公开了一种用于将伯醇催化氧化为相应羧酸的自动机器学习 (ML) 模型。使用高通量实验 (HTE) 生成了包含 3444 个数据的数据集，其中包含 282 种伯醇和 45 种条件。使用 HTE 数据和 105 个描述符，使用 AutoGluon（开源自动机器学习框架）和 KNIME（开源数据分析平台）执行多标签预测。对于 240 次反应的独立测试（20 种未见醇和 12 种条件的完整矩阵），AutoGluon 和用于产量预测的多标签预测 (AGMP) 表现出色。R 2为0.767，MAE为4.9%。该模型还表明，新生成的描述符（Y/N，反应反应性分类）是与产量预测最相关的描述符，为将 HTE 和 ML 集成到有机合成中提供了新的视角。

  The present disclosure relates to bifunctional compounds, which find utility as modulators of SMARCA2 or BRM (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a ligand that binds to the Von Hippel-Lindau E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

  本公开涉及双功能化合物，其作为SMARCA2或BRM（靶蛋白）的调节剂具有实用性。具体而言，本公开涉及包含一端结合Von Hippel-Lindau E3泛素连接酶的配体，另一端结合靶蛋白的双功能化合物，使得靶蛋白与泛素连接酶靠近以实现靶蛋白的降解（和抑制）。本公开展示了与靶蛋白降解/抑制相关的广泛药理活性。本公开的化合物和组合物用于治疗或预防由靶蛋白聚集或积累导致的疾病或紊乱。

  日期：2002.5.1

  Tandem alkylation/cyclization of indenopyrrolocarbazole 4a, a C12 carbon analogue of indolocarbazole K252c, was carried out by general solid-phase and solution-phase methods. Alkylation of fused pyrroloindenylcarbazole 4a derivatives with appropriate monoacetals of diketones afforded the corresponding C12-substituted acetal alcohols. Acid-catalyzed cyclization of these adducts yielded C12,N13-bridged

  An efficient route to acylated acyclic nucleosides containing a branched hemiaminal ether moiety is reported via three-component alkylation of N-heterocycle (purine nucleobase) with acetal (cyclic or acyclic, variously branched) and anhydride (preferentially acetic anhydride). The procedure employs cheap and easily available acetals, acetic anhydride, and trimethylsilyl trifluoromethanesulfonate (TMSOTf)
