抄録

Hydrolysis of 2-[α-amino-β-(5-nitro-2-furyl)vinyl] furan (I) gave 2-furyl 5-nitro-2-furfuryl ketone (II), and acetylation of I gave two kinds of compounds, mono- and diacetylamine. Results of other chemical reactions related to the amino group of I indicated that alkylation by propyl iodide, condensation with furfural, and amino group exchange reaction by morpholine were unsuccessful. Nine kinds of β-2-furoyl-β-(5-nitro-2-furyl)-vinyl derivatives and four kinds of 2-(2-furyl)-3-(5-nitro-2-furyl)-4, 5-disubstituted pyrrole derivatives were synthesized from II.
