Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with the enzyme ceramide galactosyltransferase (CGT), such as, for example, lysosomal storage diseases. Examples of lysosomal storage diseases include, for example, Krabbe disease and Metachromatic Leukodystrophy.
Untersuchungen an 1,3-Thiazinen, 14. Mitt. Neue und bekannte Möglichkeiten zur Darstellung von N-monosubstituierten 3-Carbamoylmercaptopropionsäuren und deren Cyclisierung zu Tetrahydro-1,3-thiazin-2,4-dionen – ein Vergleich

neuentwickelte Darstellungsmethoden für N‐monosubstituierte 3‐Carbamoylmercaptopropionsäuren 2 wurden mit bekannten Verfahren hinsichtlich Anwendungsbreite und Ausbeute verglichen und Methode C ‐ Addition von 3‐Mercaptopropionsäuremethylester an Isocyanate und folgende saure Verseifung zu 2 als überlegen erkannt. Mit Phosphorpentoxid/p‐Toluolsulfonsäure/Toluol ließen sich die Säuren 2 mit höheren Ausbeuten
ABATRACT A direct approach to N,N′-disubstituted urea/thiourea from the self-condensation reactions of isothiocyanates in water has been developed. This access tolerated a wide range of functional groups on the aromatic ring, providing a practical and environment-friendly process to N,N′-disubstituted urea/thiourea in moderate to excellent yields from safe and easily available starting materials. A
ABATRACT 已经开发了一种从异硫氰酸酯在水中的自缩合反应直接得到N , N '-二取代脲/硫脲的方法。这种访问容忍了芳环上的多种官能团,为N , N '-二取代脲/硫脲提供了一种实用且环境友好的工艺,从安全且易于获得的起始材料以中等至优异的产率。还提出了尿素脱硫自缩合反应的合理机理,并借助中间体研究的 ESI 质谱分析证明了二叔丁基过氧化物 (DTBP) 和铜催化剂在本策略中的作用。

The excellent catalytic potential of sulfated polyborate is utilized in the synthesis of (un)symmetrical ureas and benzimidazolones by heating amines or substituted OPDA and urea or N-phenylureas under a solvent-free condition at 120 °C is described. The key advantages of the present protocol are phosgene-free, and other hazardous reagents or organic solvent free, high reaction rates and yields, simple

and phenylsilane was discussed to access aryl- or alkyl-substituted ureaderivatives. This procedure was characterized by adopting hydrosilane to promote the formation of ureas directly, without the need to prepare silylamines in advance. Control reactions suggested that FeCl3 was a favorable additive for the generation of ureas, and this 1,5,7-triazabicyclo[4.4.0]dec-5-ene-catalyzed reaction might
