The benzocyclobutene-based α-amino acid derivative, ethyl 5-acetamido-2,4,5,6-tetrahydro-1H-cyclobuta[f]indene-5-carboxylate is synthesized via coupling of a benzocyclobutene-derived dibromide with ethyl isocyanoacetate as the key step, followed by hydrolysis and subsequent acetylation. This methodology is generalized in order to prepare various linearly and angularly fused indane-based α-amino acid derivatives. Georg Thieme Verlag Stuttgart - New York.
An efficient one-pot approach to phenanthrene derivatives using a catalyzed tandem Ullmann-pinacol coupling reaction
Lin, Shuang-zheng,You, Tian-pa
scheme or table, p. 9906 - 9910 (2009/04/03)
In the presence of catalyst (Ph3P)2NiCl2 and reductant Zn, the Ullmann reactions of ortho-halo aryl aldehydes generate biaryl-dialdehydes and zinc halides. Subsequently, ZnX2 can catalyze the intramolecular pinacol coupling reaction of biaryl-dialdehydes to form 9,10-dihydrophenanthrene-9,10-diols. One-pot synthesis of 9-phenanthrols can be achieved using this strategy.
