- Other 5–6 and 6–6 fused ring systems are available using this methodology, but selectivities in the final ring closure ranged from only 1:1 to 3:1 and separation of isomers was difficult; the 5–5 system did not close to any appreciable extent presumably due to ring strain and the reversibility of the Michael reaction.
