Robinson ring annulation question
« on: May 01, 2008, 11:01:17 PM »
Is this defined to be a reaction which forms a six membered ring or rather a reaction that can form any type of ring (ie 5 membered, 4 membered, bicyclic ring etc)?

The Robinson annulation forms a six-membered ring.  It's really the only way to have a conjugate addition followed by an aldol, which are the two steps of the Robinson annulation.
