研究了一系列N-磺酰基-2,5-二氢-3-取代吡咯在分子内Heck反应中的区域选择性。这些衬底在新杂环形成的环尺寸方面没有偏见。结果表明,在一定条件下观察到了很高的区域选择性,并且在烯烃最受阻的末端存在潜在的碳-碳键形成趋势。对于两个示例(3 Me和3 t Bu),进行了DFT计算,结果表明,在这两种情况下,对于碳酸盐的建模过渡态,对于实验上优选的异构体,在能量上都较低。

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 PTPN1 or PTPN2 inhibitor treatment, e.g, a cancer or a metabolic disease.
