synthesis of 2 9 dialkylated phenanthro 1 2 b 8 7 b dithiophenes via cross coupling reactions and sequential lewis acid catalyzed regioselective cycloaromatization of epoxide
Tetrahedron Letters, 2014Co-Authors: Keita Hyodo, Hikaru Nonobe, Shuhei Nishinaga, Yasushi NishiharaAbstract:Abstract Phenanthro[1,2-b:8,7-b′]dithiophene (PDT) was prepared via Suzuki–Miyaura or Negishi cross-coupling of a 2-thienylboron or -zinc compound with 1,4-Dibromobenzene, followed by Lewis acid-catalyzed regioselective cycloaromatization of the epoxide. A series of 2,9-dialkylated phenanthro[1,2-b:8,7-b′]dithiophene (PDT) derivatives could also be synthesized in good yields by Suzuki–Miyaura coupling of the brominated PDT with alkylboranes by introducing linear alkyl substituents.

Syntheses of 1-Bromo-8-methylnaphthalene and 1-Bromo-5-methylnaphthalene
The Journal of organic chemistry, 2015Co-Authors: Evans O. Onyango, Anne R. Kelley, David C. Qian, Gordon W. GribbleAbstract:The Diels–Alder reaction between 2-methylfuran and 3-bromobenzyne (3), which was generated under mild conditions from 1,3-Dibromobenzene and lithium diisopropylamide (LDA), gives a mixture of regioisomeric 1,4-dihydro-1,4-epoxynaphthalenes 4 and 5. A subsequent two-step deoxygenation affords the corresponding 1-bromo-8-methylnaphthalene (1) and 1-bromo-5-methylnaphthalene (2) in high yields.
