A NOVEL ROUTE TO LINEAR POLYCYCLIC COMPOUNDS. DIASTEREOSELECTIVE ALDOL-TYPE REACTIONS OF α-SULFONYL CARBANIONS
Ghera, E.,Ben-David, Y.
, p. 6253 - 6256 (2007/10/02)
Aromatic derivatives, bifunctionalized at vicinal benzylic positions with Br and SO2Ph groups undergo one-pot annulations with unactivated cycloalkanones.The ring closure occurs by a diastereoselective aldol-type reaction of α-sulfonyl carbanions.
