- 中文摘要: 2,6- and 2,7-dimethylanthracenes were reduced seriatim with lithium in liquid ammonia and in methylamine to their 1,4,5,8,9,10-hexahydro derivatives. Two-fold epoxidation of these tetraenes provided the cis and trans diepoxides resulting from electrophilic attack at the inner double bonds. Trans diepoxide 1 has the very unusual characteristic of lacking a .sigma. plane of symmetry but possessing an inversion center. As a consequence, the /sup 1/H NMR spectrum of C/sub i/-symmetric 1 is simplified relative to those of its isomers 5, 9, and 10.
