tetrahydropyran core was an enantioselective catalytic Mukaiyama aldolreactionusing a titanium(IV)–BINOL catalyst system. syn‐Selective reduction followed by ozonolysis led to a rapid assembly of the tetrahydropyran ring. This flexible approach also allows the synthesis of similar fragments of other complex molecules such as bryostatins and pederins. The syn‐selective coupling between the tetrahydropyran
