The One-electron Oxidation of Biphenyl-2-ylethylenes. Subsequent Chemical Reactivity Controlled by Electron Return or Proton Transfer

Biphenyl-2-ylethylenes react with (4-BrC6H4)3N.+SbCl6- to give the radical cation of the electrocyclization product which initiates a protic catalysis to the related flourenes or, in presence of 2,6-di-t-butylpyridine or water, lead

Efficient synthesis of 9-aryldihydrophenanthrenes by a cascade reaction involving arynes and styrenes

A mild, general, and transition-metal-free protocol for the synthesis of 9,10-dihydrophenanthrenes is reported. The aryne generated by the fluoride-induced 1,2-elimination of 2-(trimethylsilyl)aryl triflates undergoes an efficient cascade reaction initiated by the Diels-Alder reaction with the differently substituted styrenes leading to the formation of 9-aryl-9,10-dihydrophenanthrene derivatives in moderate to good yields.

Functionalized (Benzotriazol-1-yl)methanes as 1,1-Dipole Synthon Equivalents in Diverse Annulations to Aromatic and Heteroaromatic Rings

The title compounds 1a-e readily undergo deprotonation and subsequent reactions with the appropriate electrophiles to form intermediates of types 4 and 7 which, upon treatment with Lewis acids, cyclize to afford fused aromatics 5 and 8. Tetrahydronaphthalene 11a, 1,2,3,4-tetrahydrochromanes (11b-d, 13), indanes (16, 18), 9,10-dihydrophenanthrenes (21a-c, 25), and tetrahydro[1,2-α]indoles (28, 30) with phenyl, substituted phenyl, and thienyl substituents were prepared in this manner.
