This invention relates to oxalylamide inhibitors of Protein Tyrosine Phosphatase 1B (PTP1B) and/or T-cell Protein Tyrosine Phosphatase (TC-PTP) and/or Protein Tyrosine Phosphatases (PTPases) having an aspartic acid (Asp) in position 48 (PTP1B numbering, Chernoff et al,
Proc Natl Acad Sci USA
87: 2735-2789 (1989)) and a method of inhibiting such PTPases by exposing the enzyme to inhibitor compounds of formula 1
1
This invention also relates to (I) the design and selection of inhibitors, which bind to the active site of PTP1B and/or TC-PTP and/or PTPases having an aspartic acid (Asp) in position 48 (II) the synthesis of said inhibitors, methods for their preparation and (III) to compositions comprising the inhibitor compounds.

Two syntheses of novel 2-morpholine carboxylic acid derivatives are described. The esters were converted into 1-aza-4-oxabicyclo[3.3.1]nonan-6-one, the first example of this ring system, which was further elaborated to the ortho-methoxy benzamide derivative (2).
