Abstract
Herein, we report a protocol for PtI2-catalyzed formal three-component cascade cycloaddition reactions between γ-aminoalkynes and electron-deficient alkynes to afford highly substituted cyclohexadiene-b-pyrrolidines in good yields. On the basis of the results of the control experiments and density functional theory calculations, we present a plausible mechanism that proceeds via two key intermediates. The overall transformation involves the cleavage and formation of multiple C-C and C-N bonds and a previously unreported reaction mode of a seven-membered nitrogen heterocyclic intermediate.

Discovery of seneciobipyrrolidine derivatives for the amelioration of glucose homeostasis disorders through 4E-BP1/Akt/AMPK signaling activation. Eur J Med Chem 2021; 228:113954.

Abstract
Modulating the glucose transport in skeletal muscle is a promising strategy for ameliorating glucose homeostasis disorders. However, the complicated mechanisms of glucose transport make it difficult to find compounds therapeutically relevant molecular mechanisms of action, while phenotypic screening is thought to be an alternative approach to mimic the cell state of interest. Here, we report (±)-seneciobipyrrolidine (1a) is first found to enhance glucose uptake in L6 myotubes through phenotype-based screening. Further SAR investigation led to the identfication of compound A27 (EC50 = 2.7 μM). Proteomiic analysis discloses the unique function mechanism of A27 through upregulating the level of the eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1), subsequently enhancing the Akt and AMPK phosphorylation, thereby promoting the glucose uptake. Chronic oral administration of A27 significantly lowers blood glucose and improves glucose tolerance in db/db mice. This work is new research on seneciobipyrrolidine derivatives, providing a promising avenue for ameliorating glucose homeostasis.

Abstract
The diversified temperature-controlled hydroamination cyclization cascade reactions of homopropargylic amines and 2-butynedioates were developed for the construction of various pyrrolo- b-cyclobutenes and dihydro-1 H-azepines, respectively. This reaction actually involved an intramolecular hydroamination cyclization of homopropargylic amines to give the active dihydropyrroles intermediates, which subsequently underwent [2+2]-cycloaddition with 2-butynedioates to generate the pyrrolo- b-cyclobutenes at no more than 120 °C. Alternatively, the dihydro-1 H-azepines were directly produced at 150 °C in the reactions of homopropargylic amines and 2-butynedioates. The application of substrate scope was wide, and the corresponding products were obtained in high to excellent yields.
