The Name is 1,4-Dioxa-8-azaspiro[4.5]decane. Through research, I have a further understanding and discovery of 177-11-7. Computed Properties of C7H13NO2
This report describes a carboxylate-assisted palladium-catalysed Catellani reaction, which is compatible with ortho-amination and unactivated C(sp(2))-H arylation. This method was used to synthesize a series of 1-amino substituted dihydrophenanthridines, phenanthridines and 6H-benzo[c]chromenes. Based on kinetic isotope experiments, the kinetic curve proves that pivalic acid accelerates the reaction rate of unactivated C(sp(2))-H activation, and thus this rate can keep up with the five membered aryl-norbornene-palladacycle (ANP) intermediate.
