Efficient synthesis of a new L-shaped dimer of naphthalene, and its analogs.
Efficient syntheses of 14H-dinaphtho[1,8-bc:1',8'-fg]oxocin-14-one (2), 14H-dinaphtho[1,8-bc:1',2'-f]oxepin-14-one (3), and 2,2'(2H,2'H)-spirobi[naphtho[1,8-bc]furan] (9) are described. The putative structure of 2 has been reported previously, but the synthetic route was not reproducible. 7H-Dibenzo[c,h]xanthen-7-one (4), a known compound, was obtained by a different method. Possible reaction mechanism are proposed.
