To examine the substituenteffect on the di-π-methane (DPM) rearrangement of barrelene-like skeleton, benzopyrazinobarrelene (BPB) and benzoquinoxalinobarrelene (BQB) were utilized as the photoreaction experimental platforms. By the installation of the pyrazine, the DPM reaction was limited to aza-di-π-methane reaction only, in terms of chemoselectivity. The results of the induced regioselectivity
The Diels-Alder reactions of masked omicron-benzoquinones (MOBs) with [60]fullerene, affording novel and highly functionalized bicyclo[2.2.2]-octenone-fused [60]fullerene derivatives, are described.
