The cyclization of fluoroalkylated 3,5-dioxoesters with hydrazines, carried out in glacial acetic acid, afforded pyrazines with fluoroalkylated side-chain. The cyclization of 3,5-dioxoesters with hydroxylamine afforded hydroxylated fluoroalkylated dihydroisoxazoles. All reactions proceeded with good to very good regioselectivity. (C) 2013 Elsevier Ltd.
