-
Paragraph 00772, (2020/09/27)
Provided herein are compounds, compositions, and methods useful for inhibiting protein tyrosine phosphatase, e.g., protein tyrosine phosphatase non-receptor type 2 (PTPN2) and/or protein tyrosine phosphatase non-receptor type 1 (PTPN1), and for treating related diseases, disorders and conditions favorably responsive to PTPN 1 or PTPN2 inhibitor treatment, e.g., a cancer or a metabolic disease.

A concise and flexible synthesis of fully substituted 2-aminopyrroles via gold-catalyzed formal [3+2] cycloaddition between ynamides and isoxazoles has been developed. Under mild reaction conditions, various 2-aminopyrrole derivatives were obtained in good to excellent yields, thus providing an efficient and atom-economic way for the construction of fully substituted 2-aminopyrroles. It was all very formal: A novel gold-catalyzed formal [3+2] cycloaddition between ynamides and isoxazoles has been developed, allowing the concise and flexible synthesis of fully substituted 2-aminopyrroles. Importantly, this strategy provides new mechanistic insights and offers an atom-economic way for the construction of fully substituted 2-aminopyrroles.
REARRANGEMENTS AND CYCLIZATIONS - XIV. RING-OPENING REACTIONS OF 1,1-DIACETYLCYCLOPROPANE WITH HYDRAZINE AND HYDROXYLAMINE DERIVATIVES AS THE NOVEL SYNTHESIS OF Β-X-ETHYL SUBSTITUTED PYRAZOLES AND ISOXAZOLES
