Hello, and let me copy and paste here my comment to Eugene Kwan in the Aldol article in Wikipedia:"Hello Dr.Kwan: Thank you for making the changes in the text below the reaction equation leading to the bicyclic ketol or aldol, if you wish. The fact remains that, one cannot synthesize this compound under the "harsher" Schering reaction conditions which bypass this compound and lead to the optically active bicyclic dione. The reaction scheme as it is shown in the article has only been reported by us (ZGH and DRP); the Schering group has not reported it. Thanks again and greetings, Zoltan" (March2,2008)84.2.146.123 (talk) 08:29, 2 March 2008 (UTC)Zghajos (talk) 16:29, 2 March 2008 (UTC)

I don't think we have a copyright problem. These structures appeared in our paper in J.Org.Chem., 1974, 39, 1615- 1621 under the authorship of Zoltan G.Hajos and my coworker,David R. Parrish. The immediate source,however, comes from my own computer files. This note was made on March 29,2008 by Zoltan G. Hajos Zghajos (talk)
