Highly efficient and selective displacement of alkylthio group on acylketene O,S-acetals by organocopper reagents: A novel route to 2-alkoxy/aryloxy-1-alkenylketones
Acylketene O,S-acetals 1a-k undergo efficient and selective conjugate displacement of alkylthio group with organocopper(I) reagents to afford the corresponding 6-alkoxy/aryloxy enones 2-21 in good yields.
