On the basis of studies of the transformation of benzylic bromides into the corresponding aromatic aldehydes by treatment with N-methylmorpholine N-oxide, various methylarenes were treated either with DBDMH in the presence of AIBN in acetonitrile at reflux (Method A) or with NBS in CCl4 under irradiation with a tungsten lamp at 30 °C (Method B), followed by treatment with N-methylmorpholine N-oxide to provide aromatic aldehydes in good yields. These methods could be adopted in one-pot transformations of methylarenes into aromatic aldehydes under conditions free of less toxic reagents and transition metals. Copyright
Total synthesis of lycogarubin C utilizing the Kornfeld-Boger ring contraction
Fu, Liangfeng,Gribble, Gordon W.
scheme or table, p. 537 - 539 (2010/09/20)
An efficient synthesis of lycogarubin C (3) was completed in seven steps from the known 1-(phenylsulfonyl)indole-3-carbaldehyde in 30% overall yield, via a Diels-Alder reaction between (Z)-1,2-di(1H-indol-3-yl)ethene 9b and dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate (7), followed by a Kornfeld-Boger ring contraction to form the pyrrole ring.
