✦ Synopsis


The reactions of mono Boc-protected amino monocarboxylic acids with phosphoranylideneacetonitrile yield ylido nitriles which on ozonolysis at low temperature form labile a,b-diketo nitriles. These derivatives may be used in situ for reaction with diamines or related dinucleophiles to yield hetero derivatives of interest as unnatural amino acid building blocks.

Alkenyl tricarbonyl esters have been prepared by reaction of mono aldehydes of dibasic amino acids with tricarbonyl esters. These systems undergo reaction with diamines and other dinucleophiles by a combination of Michael addition and nucleophilic attack at the electrophilic central carbonyl to form
