The natural tetrahydroisoquinoline phylline (4) was synthesized in a specifically [1,1′-13C2]-labeled form, and fed to callus cultures of Triphyophyllum peltatum. Its incorporation into naphthylisoquinoline alkaloids, among them habropetaline A (8)

The flavor menthon (isomeric mixture of (-)-menthon and (+)-isomenthon) was obtained in good yields and selectivities by a solventless ruthenium catalyzed isomerization of the homoallylic alcohol (-)-isopulegol. In contrast to most previous assumptio

From the methanolic extracts of solid callus cultures from two species of the closely related palaeotropical plant families Dioncophyllaceae and Ancistrocladaceae seven new natural naphthoquinones were isolated, dioncoquinones A (4) and B (5) from Tr

The first total synthesis of the antimalarial naphthylisoquinoline alkaloid 5-epi-4′-O-demethylancistrobertsonine C (1a) and its—as yet unnatural—atropo-diastereomer, 1b, is described. The key step of the synthesis is the construction of the ro

Biosynthetic studies on naphthylisoquinoline alkaloids involving a specifically [1,1′-13C2]-labeled dihydroisoquinoline 7 are described. The synthesized precursor 7 was fed to callus cultures of Triphyophyllum peltatum and the isolated secondary me

[reaction: see text] A novel type of "superbiaryl", the first porphyrin dimers with an intrinsically chiral structure, has been prepared. The atropo-enantiomers were configurationally assigned by HPLC-CD combined with quantum chemical CD calculations
