Dehydrogenation of Nitrogen Heterocycles Using Graphene Oxide as a Versatile Metal-Free Catalyst under Air

Graphene oxide (GO) has been developed as an inexpensive, environmental friendly, metal-free carbocatalyst for the dehydrogenation of nitrogen heterocycles. Valuable compounds, such as quinoline, 3,4-dihydroisoquinoline, quinazoline, and indole derivatives, have been successfully used as substrates. The investigation of various oxygen-containing molecules with different conjugated systems indicated that both the oxygen-containing groups and large π-conjugated system in GO sheets are essential for this reaction. (Figure presented.).

Improved Formal Preparation of Enantiomerically Pure anti-Benzopyrene Diol Epoxide.

We report an improved, economical formal route to enantiomerically pure anti-benzopyrene diol epoxide (BPDE).A trimethylaluminum catalyzed regio- and stereoselective opening of racemic 7,8-epoxy-7,8,9,10-tetrahydrobenzopyrene with Mosher's acid delivers benzylic esters exclusively.This step is a significant improvement over the lack of regioselectivity of standard procedures.We also show that modification of the subsequent chemical steps further shortens the preparation of enantiomerically pure anti-BPDE.

1a,11b-Dihydrobenzanthrazirine. A non K-Region Polycylic Arene Imine

The synthesis of the title compound is described.Benzanthracene 8,9-oxide (6) was reacted with sodium azide in aqueous acetone and the trans-9-azido-8,9-dihydrobenzanthr-8-ol (7), so formed, was cyclized by tri-n-butylphosphine.Attempts to dehydroge
