Chemistry of Acronycine VI. Proton NMR Spectral Assignments of Acronycine and Derivatives and the Formation of Isonoracronycine.
Proton NMR assignments for acronycine and a series of derivatives are reported based on extensive homonuclear decoupling and nOe experiments at high-field. The formation of isonoracronycine ( 3) from noracronycine ( 2) under acidic conditions is discussed.
