In an attempt to improve the yields of indenols 6d and 6e we protected the alcohol functionalities of 5d and 5e with acetyl groups. However, much to our surprise, the RCM reactions of these substrates, at r.t. or at 110 °C, did not proceed to afford the acetyl-protected cyclic products and only starting material was recovered.
