The First Enantioselective Synthesis of Isoflavanoids: (R)- and (S)-Isoflavans

α-Benzylation of (+)- and (-)-N-phenylacetyl imidazolidinones with 2-O-methoxymethylbenzyl bromide, followed by reductive removal of the chiral auxiliary and cyclization, leads to isoflavans in excellent enantiomeric excess and yield.
