Total synthesis of optically active deoxyaspergillic acid from dipeptidyl aldehyde

Optically active deoxyaspergillic acid was easily synthesized by a newly developed procedure for preparation of 2(1H)-pyrazinone derivatives from L-leucyl-L-isoleucine aldehyde hydrochloride (H-L-Leu-L-Ile-H · HCl).

Amino acids and peptides. XLVII. Facile synthesis of flavacol, deoxymuta-aspergillic acid and optically active deoxyaspergillic acid from dipeptidyl aldehydes

2(1H)-Pyrazinone ring-containing natural products, flavacol, deoxymuta- aspergillic acid and finally optically active deoxyaspergillic acid, were easily synthesized by a newly developed procedure for preparation of 2(1H)- pyrazinone derivatives from dipeptidyl aldehyde hydrochlorides. The absolute configuration of natural deoxyaspergillic acid was synthetically determined as S.
