(8). Since enantiomerically pure 4 has been previously converted in five steps by Ireland into (+)-tirandamycic acid (3) and more recently by Schlessinger into (-)-tirandamycin A (1), this achievement constitutes in a strictly formal sense the total syntheses of these substances. The key step in the synthesis of 4 features the transformation of the enantiomerically pure furfuryl diol 25 into 29 by
