A NEW METHOD OF N-ACETALIZATION AND S- OR N-ETHYLATION BY MEANS OF ORTHOFORMIC ESTER
A new method is proposed for the synthesis of amidoacetals by acetalization of the imino group with orthoformic ester.The thermal instability of the obtained amidoacetals in the presence of groups having a clearly defined negative inductive effect leads to the formation of S- or N-ethylated products.
