Three new lycopodine-type alkaloids, phlenumdines A?C (1?3), have been isolated from the clubmoss Phlegmariurus nummulariifolius (Blume) Ching, and their structures were elucidated on the basis of spectroscopic data.
Total synthesis of (+)-pentamethylsalvianolic acid C
Alford, Benjamin L.,Huegel, Helmut M.
supporting information, p. 2724 - 2727 (2013/06/04)
The total synthesis of a methylated analogue of (+)-Salvianolic acid C has been achieved. Key aspects of the synthetic route include an economical Cu(i) acetylide coupling, unique carboxyl activation conditions via microwave irradiation and a novel lipase catalysed kinetic resolution of a racemic mixture of secondary alcohol Danshensu. The preparation of this methylated analogue will not only improve the bioavailability, but also enable access to new and wider bioactivity applications for (+)-Salvianolic acid C.
Tricyclic benzomorphan analogues by intramolecular Oxa-Pictet-Spengler reaction
Wunsch,Zott
, p. 2307 - 2310 (2007/10/02)
The key step in the regio- and stereoselective preparation of the benzomorphan analogues 9, 10a, 10b, 14 and 15 is an intramolecular Oxa-Pictet-Spengler reaction. Masked as an acetal the carbonyl component is connected via an amide to the 2-phenylethanol component (7, 12).
