摘要：

Di‐tert—butylacetylenedicarboxylate 1—surprisingly not synthesized before—is remarkable from a chemical standpoint. Its cyclotrimerization shows that the tert‐butyl groups do not exert strong steric hindrance. Ready cleavage (without base) of the esters obtained from 1 is of advantage. (Formula Presented.)
