1,1-BIS(PHENYLSULFONYL)ETHYLENE 化學(xué)特性,用途語,生産方法
使用
1,1-Bis(phenylsulfonyl)ethylene was used in the preparation of α,α-disubstituted alpha-amino acid derivatives.
主な応用
1,1-Bis(phenylsulfonyl)ethylene (1,1-BPSE) is a powerful Michael acceptor and dienophile; reagent for two-carbon homologation of ketones; synthetic equivalent of ethylene in Diels-Alder reactions and of ethylene 1,2-dipole in cycloadditions
[1].
製造方法
1,1-Bis(phenylsulfonyl)ethylene can be prepared via careful oxidation of the corresponding ketene
dithioacetal or via Mannich condensation of bis(phenylsulfonyl)methane with paraformaldehyde and a
secondary amine followed by elimination with acids
[2].
