Four‐component, quadruple cascade, one catalyst: An asymmetric four‐component (ABC2) quadruple cascadereaction initiated by oxa‐Michaeladdition of aliphatic alcohols to acrolein is reported (see scheme) to provide high yields of trisubstituted highly functionalized cyclohexene carbaldehydes with excellent diastereomeric and complete enantiomeric control. This process can be explained by an iminium
