Indium(III)-catalyzed addition of diethyl acetamidomalonate to terminal alkynes: an efficient approach to beta-branched alpha-amino acids.
The indium(III)-catalyzed Markovnikov addition of active methylene compounds to terminal alkynes has been expanded further to include diethyl acetamidomalonate. This reaction has been studied, and a practical approach to beta-branched alpha-amino acids was developed.
