A chelation effect on the pathway between intramolecular hydrodimerization and pinacol coupling.
[structure: see text] Depending upon the reaction conditions, the reductive cyclization affords either the pinacol or normal hydrodimerization-type products. This selectivity is highly dependent upon the substitution at the beta-position of the enones.
