A new approach is demonstrated for the synthesis of macrotetralides through an olefin metathesis reaction using Grubbs' second‐generation catalyst with titanium isopropoxide as a cocatalyst. This study demonstrates a tandem self‐cross and ring‐closing metathesis approach to form macrocyclic ring systems with excellent ( E ) selectivity. The reaction was optimized with regard to functional group, catalyst, solvent, Lewis acid, concentration, and temperature.
