Disclosed in an alicyclic end-capping agent for a heterocyclic compound, which is represented by the formula [I]: ##STR1## wherein X is CO, O, S, CH.sub.2 or substituted CH.sub.2, Y.sub.1 -Y.sub.6 are halo, H, NO.sub.2, aryl, alkaryl, arylalkyl or alkyl ether, and Z is ##STR2## (Q.sub.1 is --NH.sub.2, --SH, --OH or ##STR3## (Q.sub.2 is H, or monovalent aliphatic or amomatic group). Also disclosed is an addition-curable quinoxaline resin oligomer having the above-mentioned alicylic end-capping agents at both terminals of oligomer. This oligomer is useful especially for an intermediate material for a fiber-reinforced composite.
