Squarate 2 was not suitable since the nucleophilic addition did not occur at -78°C. Furthermore, α-diazo carbonyl compounds were used since derivatives of diazoalkane such as (trimethylsilyl)diazomethane were too unstable [decomposition during workup gave only 12% of the cyclopentenedione (13: R = TMS) as a product].

In an exception, the (Z)-isomer was a minor product in the Rh-catalysis of 12a (entry 6), probably because of coordination with a Rh center.
