Direct synthesis of G-2N
Kraus, George A.,Zhao, Guohua
, p. 2770 - 2773 (1996)
The synthesis of angularly fused quinone natural products has been achieved using a photoenolization reaction and a Diels-Alder reaction in the key carbon-carbon bond forming steps.
Formylation of electron-rich aromatic rings mediated by dichloromethyl methyl ether and TiCl4: Scope and limitations

Here the aromatic formylation mediated by TiCl4 and dichloromethyl methyl ether previously described by our group has been explored for a wide range of aromatic rings, including phenols, methoxy- and methylbenzenes, as an excellent way to produce aromatic aldehydes. Here we determine that the regioselectivity of this process is highly promoted by the coordination between the atoms present in the aromatic moiety and those in the metal core.
Acid-labile cys-protecting groups for the Fmoc/tBu strategy: Filling the gap
Gongora-Benitez, Miriam,Mendive-Tapia, Lorena,Ramos-Tomillero, Ivan,Breman, Arjen C.,Tulla-Puche, Judit,Albericio, Fernando
supporting information, p. 5472 - 5475,4 (2012/12/12)
To address the existing gap in the current set of acid-labile Cys-protecting groups for the Fmoc/tBu strategy, diverse Fmoc-Cys(PG)-OH derivatives were prepared and incorporated into a model tripeptide to study their stability against TFA. S-Dpm proved to be compatible with the commonly used S-Trt group and was applied for the regioselecive construction of disulfide bonds.
Synthesis of novel structurally simplified estrogen analogues with electron-donating groups in ring A
Tietze, Lutz F.,Vock, Carsten A.,Krimmelbein, Ilga K.,Nacke, Linda
experimental part, p. 2040 - 2060 (2009/12/27)
A library of 25 novel estrogen analogues were prepared in five to eight steps from mostly commercially available substituted anisoles via bromination, formylation, Corey-Fuchs reaction, elimination, and Sonogashira reaction. Georg Thieme Verlag Stuttgart.
