A novel DMAP‐mediated Rauhut‐Currier/ oxa ‐Michael addition cascade reaction of hydroxylphenyl‐substituted para ‐quinone methide with allenoate was reported for the first time. A series of functionalized chromenes were successfully obtained with moderate to good yields under this one‐pot cascade reaction. The chromene products could be easily transformed into different derivatives and a plausible mechanism was proposed to elucidate this novel reaction.
