Synthetic applications of bis(iminophosphoranes). One-pot preparation of rigid bicyclic guanidines
摘要:
A one-pot synthesis of [6 + 6], [6 + 7], and [6 + 8] bicyclic guanidines based on a new method of dihydropyrimido annelation, which involves reaction of bis(iminophosphoranes) with aryl isocyanates or isothiocyanates is described. The method is also applicable for the preparation of chiral bicyclic guanidines.
