The disclosure relates to compounds and pharmaceutical compositions capable of modulating the hydroxysteroid 17-beta dehydrogenase (HSD17B) family member proteins including inhibiting the HSD17B member proteins, e.g. HSD17B13. The disclosure further relates to methods of treating liver diseases, disorders, or conditions with the compounds and pharmaceutical compositions disclosed herein, in which the HSD17B family member protein plays a role.
intermediates for synthesizing valuable nitrogen-containing compounds, but their potential applicability is limited by the available synthetic methods. To address this issue, we report a scandium(III) triflate catalyzed direct synthesis of N-unprotected ketimines. Using commercially available reagents and Lewis acid catalysts, ketones were directly transformed into the corresponding N-unprotected ketimines
10,11-Dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imines, derivatives and pharmaceutically acceptable salts thereof are useful as antianxiety agents, as muscle relaxants and in the treatment of extrapyramidal disorders such as in Parkinson's disease. They are prepared by treatment of a 5H-dibenzo[a,d]cyclohepten-5-one with ammonia to give the 5-imine, acylation of the imine, treatment of the protected imine with an organolithium to provide the 5-substituted-5-acylamino compound, treatment with acid or base to cause ring closure to a 5-substituted-5,10-acylimino compound followed by removal of the protecting group, either hydrolytically or hydrogenolytically.
The present invention provides a polymerizable compound having high storage stability without causing crystal precipitation when added to a polymerizable composition. The present invention also provides a polymerizable composition containing the compound. When the filmy polymer produced through polymerization of the polymerizable composition is irradiated with UV light, it hardly discolors or peels from substrate. Further, the present invention provides a polymer produced through polymerization of the polymerizable composition and an optically anisotropic body using the polymer.

Herein, we summarize our recent efforts toward developing catalytic methods for the synthesis of N-unsubstituted ketimines and their applications to one-pot reactions for producing various nitrogen-containing compounds. This account provides detailed background, optimization, scope, and mechanistic information. We hope this work will stimulate future studies on the implementation of N-unsubstituted
