Abstract

Further Contributions to the Synthesis of (+)‐Aspicilin There are two reasons to try to find out. whether the initial and final parts of the ‘photochemical synthesis’ of the 18‐membered lichen macrolide (+)‐aspicilin ( 5a ) can be improved ( cf. Schemes 1 and 2 ). This synthesis acts as an indicator for the utility of the earlier introduced photolactonization and as a source of large‐ring‐sized lactones, objects for computer‐assisted conformational analysis.
