alpha-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 beta-bromo-alpha-methoxy hydrazones (11), which after hydrolysis and HBr-elimination yields the alpha-methoxy enals or alpha-methoxy enones (13), respectively.
