Highly stereoselective synthesis of cyclopentanes bearing four stereocentres by a rhodium carbene-initiated domino sequence – The reaction proceeds by a carbene-initiated domino sequence consisting of five distinct steps: rhodium-bound oxonium ylide formation, [2,3]-sigmatropic rearrangement, oxy-Cope rearrangement,
The proton-transfer tautomerization form (normally named keto in the S 0 state and keto* in the S 1 state) has charge redistribution characteristic, which are very fascinating towards the application.

A compound containing a carbonyl group (C=O) is normally in rapid equilibrium with an enol tautomer, which contains a pair of doubly bonded carbon atoms adjacent to a hydroxyl (−OH) group, C=C-OH. The keto form predominates at equilibrium for most ketones. Nonetheless, the enol form is important for some reactions.
According to the researchers, formation of these enols can’t be explained purely by keto-enol tautomerization–the simple isomerization.
