Intramolecular Morita-Baylis-Hillman adducts via sequential MBH and ring-closing-metathesis reactions

Using a tandem Morita-Baylis-Hillman (MBH) and ring-closing-metathesis (RCM) sequence, an alternative high yielding method for the construction of intramolecular Morita-Baylis-Hillman (IMBH) mono- and bicyclic functionalized cycloalkenols is reported.
