• , DIBAH) occurs normally by 1,2-attack, this being a key step in the well known "carbonyl transposition" of 1,3-diketone enol ethers into enones (R3O-CR=CR1-COR2 → R-CO-CR1=CHR2). [11][12][13][14][15] Prior to our work there were no reports on the reduction of isoflavones containing free hydroxy groups
