    IODODECARBOXYLATION OF α-CARBOXYLATE, α-CINNAMOYL KETENE CYCLIC DITHIOACETALS
    摘要:
    The iododecarboxylation reaction of alpha-carboxylate, alpha-cinnamoyl ketene cyclic dithioacetals 2 was successfully performed with iodine as halogenation reagent and in water insensitive media. This reaction provides a mild and efficient method for the preparation of alpha-iodo, alpha-cinnamoyl ketene cyclic dithioacetals 3 which are important kinds of potential new intermediates to be valued.

  • Intramolecular Aza-Anti-Michael Addition of an Amide Anion to Enones: A Regiospecific Approach to Tetramic Acid Derivatives
    作者:Xihe Bi、Jingping Zhang、Qun Liu、Jing Tan、Bing Li
    DOI:10.1002/adsc.200600542
    日期:2007.10.8
    A novel intramolecular aza-anti-Michael addition was disclosed in the one-pot reactions between 3-oxobutanamides and aryl (heteroaryl) aldehydes under basic conditions, in which amide anions regiospecifically attacked the α-carbon of an enone fragment, providing a new route to biologically important tetramic acid derivatives. An explanation for the unexpected regioselectivity is proposed based on the
