Strasser, Simone,Pump, Eva,Fischer, Roland C.,Slugovc, Christian
, p. 1143 - 1151 (2015)
A series of electron-rich second-generation cis-dichloro ruthenium aldehyde-chelating benzylidene complexes was prepared, characterized, and tested in typical ring-opening metathesis polymerization (ROMP) experiments. The benzylidene precursors were prepa
Preparation method of aporphine alkaloid
-
Paragraph 0055-0058; 0120-0121, (2021/06/09)
The invention discloses a preparation method of aporphine alkaloid as shown in a formula III. The method comprises the following steps: taking a benzaldehyde compound as shown in a formula III-0 as a raw material, and sequentially carrying out Wittig reaction, Pictet-Spengler reaction, Heck reaction and palladium carbon hydrogen deprotection. A bromine-containing benzaldehyde derivative is selected as a raw material, the carbon-carbon coupling co-production rate and the reaction rate are increased through bromine atoms, and the reaction activity is improved; benzyl chloroformate is adopted for NH protection, and an electron withdrawing group is introduced, so that the reaction yield can be improved; and a styrene methyl ether derivative directly reacts with an acylated phenylethylamine derivative in an acid catalysis system by adopting a one-pot method so as to obtain benzyl tetrahydroisoquinoline. The preparation method has the advantages of mild reaction conditions, low toxicity of used reagents, easily available raw materials, convenient post-treatment and simpler reaction route compared with previous reports, and can be suitable for various reaction substrates.

supporting information, p. 3756 - 3761 (2021/07/14)
We describe here a controlled approach to C1-symmetrical cyclotriveratrylenes (CTVs). In this approach dimers are synthesized through Barluenga boronic coupling (BBC) and after borylation, the last aromatic ring is introduced by a second BBC. After functional transformations of the trimers, the CTVs are formed using intramolecular SEAr. (Figure presented.).
