Site selective oxidation of some azaspiroundecanes using Beauvaria sulfurescens ATCC 7159
Abstract
The micro-organism Beauvaria sulfurescens ATCC 7159 converted the bicyclic compounds (5), (12), (17), and (19) into the corresponding oxygenated products (6), (13), (18), and (20) respectively. The amide (9) gave the alcohols (10) and (11) under similar conditions while the isomeric substrate (14) gave equal amounts of the hydroxyamides (15) and (16).
