Practical regioselective method for (E)-enol ehter

A new practical and highly regioselective synthetic method for (E)-enol ether is reported. (E)-enol ethers (E:Z = 93:7-99:1) were prepared from the corresponding enol acetates (E:Z?3:1) in two steps by bromination and anti- elimination of α-bromodialkylac

SELENIUM CATALYZED CONVERSION OF VINYL HALIDES INTO α-ALKOXY ACETALS

The reaction of vinyl halides with phenylselenenyl chloride in alcohols affords α-alkoxy acetals and diphenyl diselenide which can be oxidized to PhSe cations by nitrate or persulfate anions.The reaction can be carried out with catalytic amounts of PhSeCl or PhSeSePh.The reaction proceeds through the formation of the methoxyselenenylation product which then suffers solvolysis.Under controlled conditions, the 1-phenyl-1-methoxy-2-bromo-2-phenylselenenyl ethane was isolated from the reaction of β-bromostyrene and PhSeCl in methanol.Several deselenenylation reactions of this α-halogenoselenide are reported.
