Starting from a polymer-bound olefin, iterative application of nitrile oxide 1,3-dipolar cycloaddition and selenide oxidation/elimination steps were employed to deliver a polymer-bound triisoxazoline that can be liberated from the resin by transesterification. When four nitroseleno ethers (2-5) and four capping nitroalkanes (6-9) were employed, a triisoxazoline library (V) of 64 positional isomers
