摘要：
The reaction of 4-hydroxy-4-methyl-2-pentanone with ethyl cyanoacetate in the presence of ammonium acetate is a consecutive-parallel multistep domino process. The regioselectivity of the reaction is due to the direction of the electrophilic attack of the intermediate formed in the first step, namely, ethyl 2-cyano-3,5-dihydroxy-3,5-dimethylhexanoate. © 2007 Springer Science+Business Media, Inc.
