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

Mehta, Barun K.,Dhar, Sanchita,Ila,Junjappa

, p. 9377 - 9380 (2007/10/02)

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.
