Asymmetric Synthesis of the (S)-1,1-Dioxido-isothiazolidin-3-one Phosphotyrosine Mimetic via Reduction of a Homochiral (R)-Oxido-isothiazolidin-3-one
摘要:
The first asymmetric synthesis of the (S)-1,1-dioxido-isothiazolidin-3-one ((S)-IZD) pTyr mimetic, which has been incorporated into the recently reported potent protein tyrosine phosphatase 1B (PTP1B) inhibitors, is presented herein. The key reaction is the reduction of the (R)-oxido-isothiazolidin-3-one heterocycle with excellent regiochemical and stereochemical control (> 98% ee; 82% yield).
