ChemInform Abstract
The described method offers an easy access to a broad rang of carbo- and heterospirocyclic frameworks. Thus, the reaction of the β-aminocrotonate (VII) with the iron complex salt (II) affords diastereoselectively the spiro compound (VIII) which can be easily transformed to the spirohexenone (XI).
