Preparation of N-p-Tosylaldimines by the Intramolecular Photo-Imino Group Migration of Naphthodithiin-1-N-tosylsulfilimines
Naphthodithiin-1-N-tosylsulfilimines (4) were prepared by the reaction of napthodithiins with chloramine-T.Photolysis of 4 undergoes intramolecular imino group rearrangement to give N-tosylaldimines quantitatively together with naphthalene
One-Pot Diels-Alder Reaction of N-p-Tosylaldimines Generated by BF3-Et2O Catalyzed Transformation of Naphthodithiin-1-N-p-tosylsulfilimines
Naphthodithiin-1-N-p-tosylsulfilimines (4) were prepared by the reaction of naphthodithiin with chloramine-T.Treatment of 4 with dienes in the presence of BF3-Et2O afforded the imino Dields-Alder products via N-p-tosylaldimines produced in
