Dehydroamino acid derivatives from D-arabinose and L-serine: synthesis of models for the azinomycin antitumor antibiotics
摘要:
Synthesis of aldehydes 17 from D-arabinose and 31 from L-serine provided key precursors for the generation of highly functionalized dehydroamino acid derivatives upon condensation with glycyl phosphonates. Subsequent bromination and intramolecular addition/elimination afforded the azabicyclo[3.1.0]hex-2-ylidene ring system postulated to exist in the azinomycin antitumor antibiotics.
