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.

Dehydroaminoacid dienes 11A-C were synthesized and subjected to the Sharpless asymmetric dihydroxylation, producing diols 13A-C. Diol 13A was further converted to the naphthoate derivative 18 and to the triacetate 19.
