α-Methoxylation of Unsaturated Carbonyl Compounds
Feuerer, Albert,Severin, Theodor
, p. 6026 - 6029 (1994)
α-Methoxylation of enals or enones can be performed in high yield by a simple one-pot reaction sequence: Bromination of unsaturated hydrazones, HBr-elimination, and addition of methanol leads to the formation of β-bromo-α-methoxy hydrazones (11), which af
