Synthesis of Organotin Substituted Tricyclic Macrodiolides

The radical addition of triorganotin hydrides, R3SnH (R=n-butyl, phenyl, neophyltin), to four unsaturated diesters of (11R,12R)-9,10-dihydro-9,10-ethaneanthracene-11,12-dimethanol leads to products of cyclohydrostannation with an average yield of around 80%. Whereas the addition of these hydrides to...
