Direct Preparation of Guanidine from Trichloroacetamide. A Potentially Important Method to (-)-Tetrodotoxin

Trichloroacetamides obtained via Overman sigmatropic rearrangement were converted into dibenzyl guanidines.The key step was conversion of carbodiimide intermediate into guanidine by scandium or ytterbium trifluoromethane-sulfonates.This method was a
