摘要: A general strategy for the amino acid homologation via Blaise reaction and subsequent reduction is presented. This involves preparation of protected α-amino nitriles from corresponding acids, followed by zinc-mediated condensation tert-butyl bromoacetate, to give imidazolidones after iminozincate cyclization. Reduction gave saturated imidazolidinones with cis or trans stereochemistry, depending on conditions. was applied nonfunctionalized acids functionalized such as serine aspartic acid. Additionally, acidic hydrolysis chiral 4-aminopyrrolidones described.
