- The structures assigned to the compounds reported herein were confirmed by infrared, proton magnetic resonance and mass spectrometric data. NMR spectra were determined on a Varian T-60-A in CDCl3 and gc-ms spectra on a Finigan 1015C. Melting points were taken on a Thomas-Hoover melting point apparatus and are uncorrected
