Abstract

The palladium(0)-catalyzed heteroannulation of 2,2-diphenol and the biscarbonate of butenediol afforded quantitatively rac-(SA,6R)-6-vinyl-6,7-dihydrodibenzo[e,g][1,4]dioxocine. The use of chiral ligands gave this unique stereoisomer with ee up to 30%.

Keywords: Dibenzo[1,4]dioxocin, palladium, annulation, asymmetry
