On January 1, 2021, Ohsawa, Kosuke; Ochiai, Shota; Kubota, Junya; Doi, Takayuki published an article.Electric Literature of 98946-18-0 The title of the article was Gold-catalyzed amide/carbamate-linked N,O-acetal formation with bulky amides and alcohols. And the article contained the following:
A gold-catalyzed N,O-acetal formation was established to construct an amide/carbamate-linked N,O-acetal substructure with bulky alcs. The acyliminium cation species generated from o-alkynylbenzoic acid ester in the presence of a gold catalyst is highly reactive and underwent nucleophilic attack of various bulky alcs. and phenols at room temperature under neutral conditions, leading to the corresponding N,O-acetals in yields of 34-89% with good functional group tolerance. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Electric Literature of 98946-18-0
