Abstract
Ru(II)-catalyzed condition-controlled divergent coupling between 3-aryl-2H-benzoxazin-2-ones and benzoquinones has been realized under operationally simple conditions, affording a series of structurally stable spiropyrans and valuable arylquinones. The potential of this method is also demonstrated by scale-up synthesis and derivatization. Additionally, an unprecedented cycloruthenated complex has been identified as a key intermediate.

Abstract
In this work, new derivatives (substituted 9-methyl-9-arylxanthenes) of xanthene compounds (5a-l) of possible biological significance were synthesized by developing a new synthesis method. In order to obtain xanthene derivatives, the original alkene compounds to be used as the starting materials were synthesized in four steps using appropriate reactions. A cyclization reaction by intramolecular Friedel-Crafts alkylation was carried out in order to synthesize the desired xanthene derivatives using the alkenes as starting compounds. The intramolecular Friedel-Crafts reaction was catalyzed by trifluoroacetic acid (TFA) and provided some novel substituted 9-methyl-9-arylxanthenes with good yields at room temperature within 6-24 hours. As a result, an alkene compound was used for activation with TFA in the synthesis of xanthene through intramolecular Friedel-Crafts alkylation for the first time.

Abstract
A mild ruthenium(ii)-catalyzed spiroannulation between benzamides and naphthoquinones is developed for the succinct synthesis of biologically relevant spiro-isoindolinone scaffolds. A base promoted transannulation of spirocyclic products en route to valuable benzo[b]phenanthridinetriones in good yields has also been accomplished.

Abstract
A series of N-phenyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine derivatives with NF-κB inducing kinase (NIK) inhibitory activity were obtained through structure-based drug design and synthetic chemistry. Among them, 4-(3-((7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)-4-morpholinophenyl)-2-(thiazol-2-yl)but-3-yn-2-ol (12f) was identified as a highly potent NIK inhibitor, along with satisfactory selectivity. The pharmacokinetics of 12f and its ability to inhibit interleukin 6 secretion in BEAS-2B cells were better than compound 1 developed by Amgen. Oral administration of different doses of 12f in an imiquimod-induced psoriasis mouse model showed effective alleviation of psoriasis, including invasive erythema, swelling, skin thickening, and scales. The underlying pathological mechanism involved attenuation of proinflammatory cytokine and chemokine gene expression, and the infiltration of macrophages after the treatment of 12f. This work provides a foundation for the development of NIK inhibitors, highlighting the potential of developing NIK inhibitors as a new strategy for the treatment of psoriasis.
