Abstract

Radical-mediated opening of a trisubstituted epoxy alcohol using cp2TiCl was followed by diastereoselective reduction of the resulting product with a centrally located methylene group, flanked on both sides by two chiral hydroxyl-bearing carbons, to build all the three chiral centers of (+)-prelactone B 1 in their desired stereochemistries leading to the total synthesis of the molecule.
