Abstract
General and efficient strategies for highly diastereoselective synthesis of divergent heterocyclic scaffolds through desymmetric [3+3] cycloaddition of p-quinamines with 1,3-dipole surrogates hydroximoyl halides and α-halohydroxamates have been developed. This synthetic protocol provided a variety of heterocyclic architectures containing 1,2,4-oxadiazine and hydroquinoxaline skeletons in good yields with a wide substrate scope.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disease that is difficult to treat. Extracellular amyloid is the principal pathological criterion for the diagnosis of AD. Amyloid β (Aβ) interacts with various receptor molecules on the plasma membrane and mediates a series of signaling pathways that play a vital role in the occurrence and development of AD. Research on receptors that interact with Aβ is currently ongoing. Overall, there are no effective medications to treat AD. In this review, we first discuss the importance of Aβ in the pathogenesis of AD, then summarize the latest progress of Aβ-related targets and compounds. Finally, we put forward the challenges and opportunities in the development of effective AD therapies.

Abstract
The recent approval of aducanumab for Alzheimer's disease has heightened the interest in therapies targeting the amyloid hypothesis. Our research has focused on identification of novel compounds to improve amyloid processing by modulating gamma secretase activity, thereby addressing a significant biological deficit known to plague the familial form of the disease. Herein, we describe the design, synthesis, and optimization of new gamma secretase modulators (GSMs) based on previously reported oxadiazine 1. Potency improvements with a focus on predicted and measured properties afforded high-quality compounds further differentiated via robust Aβ42 reductions in both rodents and nonhuman primates. Extensive preclinical profiling, efficacy studies, and safety studies resulted in the nomination of FRM-024, (+)-cis-5-(4-chlorophenyl)-6-cyclopropyl-3-(6-methoxy-5-(4-methyl-1H-imidazole-1-yl)pyridin-2-yl)-5,6-dihydro-4H-1,2,4-oxadiazine, as a GSM preclinical candidate for familial Alzheimer's disease.

Abstract
γ-Secretase (GS) is one of the most attractive molecular targets for the treatment of Alzheimer's disease (AD). Its key role in the final step of amyloid-β peptides generation and its relationship in the cascade of events for disease development have caught the attention of many pharmaceutical groups. Over the past years, different inhibitors and modulators have been evaluated as promising therapeutics against AD. However, despite the great chemical diversity of the reported compounds, a global classification and visual representation of the chemical space for GS inhibitors and modulators remain unavailable. In the present work, we carried out a two-dimensional (2D) chemical space analysis from different classes and subclasses of GS inhibitors and modulators based on their structural similarity. Along with the novel structural information available for GS complexes, our analysis opens the possibility to identify compounds with high molecular similarity, critical to finding new chemical structures through the optimization of existing compounds and relating them with a potential binding site.
