Biosynthesis of the amaryllidaceae alkaloid Galanthamine
Abstract Application of radioactively as well as 13C-labelled 4′-O-methylnorbelladine to organs of field grown Leucojum aestivum plants resulted in an optimal incorporation into galanthamine (27%),Expand
Hypervalent iodine oxidation of p-alkoxyphenols and related compounds : a general route to p-benzoquinone monoacetals and spiro lactones
Oxydation de dimethoxy-, trimethoxy-, carboxy-2', ethyl, carboxy-2' ethoxy- et hydroxy-2' ethylphenols a l'aide du bis-trifluoroacetoxyiodo benzene
Hypervalent Iodine Reagents for the Oxidation of Alcohols and Their Application to Complex Molecule Synthesis
Hypervalent iodine(V) derivatives such as 2-iodoxybenzoic acid (IBX) and Dess–Martin periodinane [DMP; 1,1,1-tris(acetyloxy)-1,1-dihydro-1,2-benziodoxol-3-(1H)-one] have been used widely for theExpand
Oxidative Intramolecular Phenolic Coupling Reaction Induced by a Hypervalent Iodine(III) Reagent: Leading to Galanthamine-Type Amaryllidaceae Alkaloids
By extending our oxidative phenol-coupling reactions using a hypervalent iodine(III) reagent, a versatile synthetic procedure for the galanthamine-type Amaryllidaceae alkaloids was accomplished. TheExpand
An Oxidative Intramolecular Phenolic Coupling Reaction for the Synthesis of Amaryllidaceae Alkaloids Using a Hypervalent Iodine(III) Reagent
The oxidative intramolecular phenolic coupling reaction of norbelladine derivatives (1) was investigated with the aim of preparing amaryllidaceae alkaloids. Spirodienone compounds (2), which areExpand
The synthetic and biological studies of discorhabdins and related compounds.
Various analogues of the marine alkaloids, discorhabdins, have been synthesized. The strategy contains spirocyclization with phenyliodine(III) bis(trifluoroacetate) (PIFA), oxidative fragmentation ofExpand
A novel and efficient oxidative biaryl coupling reaction of phenol ether derivatives using a combination of hypervalent iodine(III) reagent and heteropoly acid.
A novel and efficient oxidative biaryl coupling reaction of phenol ether derivatives using a combination of hypervalent iodine(III) reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA), andExpand
Synthesis of the Marine Pyrroloiminoquinone Alkaloids, Discorhabdins
Many natural products with biologically interesting structures have been isolated from marine animals and plants such as sponges, corals, worms, etc. Some of them are discorhabdin alkaloids. TheExpand
