Reaction Steps

The compound 89 (245 mg, 0.6 mmol) was converted to the iminodicarboxylate with N-octadecanyloxycarbonyl isocyanate prepared from 1-octadecanol (297 mg, 1.1 mmol) and N-chloroarbonyl isocyanate (106 mg, 1 mmol) in the same manner as the example 82 to give the compound 100 (295 mg, 66%).
