Stereochemistry of the intramolecular cyclization products of methyl 2-bromo-5-(4-hydroxyphenyl)hexanoate: Synthesis of trans- and cis-1,4-dimethyltetralin
Autor: Tetsuaki Tanaka, Naoyoshi Maezaki, Chuzo Iwata, Takafumi Fusaka
Publikováno v: Chemical and Pharmaceutical Bulletin. 32:447-451
The stereochemistry of the spirodienones (2) obtained by the intramolecular cyclization of methyl 2-bromo-5-(4-hydroxyphenyl) hexanoate (1) was established by carbon-13 nuclear magnetic resonance spectral analysis and chemical transformation to trans

Publikováno v: Chemical and Pharmaceutical Bulletin. 35:544-552
Total synthesis of (±) -solavetivone (1), a spirovetivane phytoalexin, was achieved. The metal catalyzed decomposition of the phenolic diazoketone (8) gave the spiro-dienone (6), selective reduction of which afforded the hydroxy-enone (5). The regio
