reactions of a variety of aldehydes with aqueous ammonia, molecular iodine, and O,O-diethyl dithiophosphoric acid readily afford the corresponding primarythioamides. This is an inexpensive, practical, and metal-free way of accessing various thioamides from aldehydes in aqueous media. The pure products are obtained simply by filtration followed by successive washing with aqueous sodium thiosulfate

The present invention relates to a composition for use in treating a glioma or ameliorating the effects of a glioma, particularly glioblastoma, wherein said composition comprises a first active agent selected from the group consisting of a compound of formula (I), or a pharmaceutically acceptable salt thereof, (I) and a second active agent, which is temozolomide, or a pharmaceutically acceptable salt thereof; and a pharmaceutically acceptable carrier.
We herein report a general, practical, and highly efficient method for asymmetricsynthesis of a wide range of chiral vicinal diamines via reductive coupling of imines templated by chiral diboron. The protocol features high enantioselectivity and stereospecificity, mild reaction conditions, simple operating procedures, use of readily available starting materials, and a broad substrate scope. The method

iron oxide catalyst (Fe2O3@NC) for nitrile synthesis. The iron oxide nanoparticles were uniformly wrapped in the N-doped carbon matrix to prevent their aggregation and leaching. Fe2O3@NC-800, which was subjected to carbonization at 800 °C, exhibited excellent activity, selectivity, and stability in the catalytic ammoxidation of aromatic aldehydes to aromaticnitriles. This study may provide a new method
氮掺杂碳催化剂由于其在催化应用方面的诸多优势而吸引了越来越多的研究关注。在此,使用具有成本效益的可再生生物质壳聚糖来制备经氧化铁催化剂(Fe 2 O 3 @NC)改性的N掺杂碳,用于腈合成。氧化铁纳米颗粒均匀地包裹在N掺杂的碳基质中,以防止其聚集和浸出。Fe 2 O 3 @ NC-800在800°C的温度下碳化,在芳族醛催化氨氧化为芳族腈的过程中表现出出色的活性,选择性和稳定性。这项研究可能会提供一种新的方法来制造一种高效且具有成本效益的合成腈的催化剂体系。

A novel method for the preparation of N-chloroaldimines from commonly available aromatic aldehydes has been developed. The reaction proceeded effectively by two steps: aldehydes were initially transformed into imines and then chloro-substitution with NaClO2 gave the N-chloroaldimines. This simple protocol allows for the preparation of a variety of aromatic N-chloroaldimines in moderate to excellent
