| Abstract: | The two isopavines (le and lf) have been synthesised, and the former has been found to correspond to the structure of the alkaloid reframoline. The two related pavines were isolated and identified as by-products. In one case some evidence was obtained for a C1→C3-benzyl migration in the isoquinoline system.Although it has proved to be impossible to distinguish between the two isopavines by spectral methods, a significant difference was observed in the UV spectra of the derived methine bases in alkaline solution. |
