Ej. Moran et al., DEHYDROAMINO ACID-DERIVATIVES FROM D-ARABINOSE AND L-SERINE - SYNTHESIS OF MODELS FOR THE AZINOMYCIN ANTITUMOR ANTIBIOTICS, Journal of organic chemistry, 58(27), 1993, pp. 7848-7859
Synthesis of aldehydes 17 from D-arabinose and 31 from L-serine provid
ed key precursors for the generation of highly functionalized dehydroa
mino acid derivatives upon condensation with glycyl phosphonates. Subs
equent bromination and intramolecular addition/elimination afforded th
e azabicyclo[3.1.0]hex-2-ylidene ring system postulated to exist in th
e azinomycin antitumor antibiotics.
