Notes: La biosynthèse de la proferrorosamine A produite par Pseudomonas roseus fluorescens est inhibée par le tryptophane et cette inhibition est levée par l'acide shikimique. A la suite de l'ensemble des résultats acquis, des hypothèses concernant le rôle métabolique de la proferrorosamine A sont formulées et discutées.

Notes: The synthesis, some dyeing, and fastness properties of several new dispersed and acid dyes derived from the amino-benzotriazoles 1 & 3 and the aminobenzimidazoles 2a, 2b & 4 are described. The suitability of the amino derivatives 1, 2a, 2b, 3 & 4 as bases for azoic dyeing has also been studied. Several interesting observations between the properties of some synthesised dyes and the corresponding benzene or naphthalene analogues are cited.

Notes: Alkylation of 5-nitroindazole (I) with dimethyl sulphate and/or diethyl sulphate in presence of sodium hydroxide yields mixtures containing more 2-alkylated than 1-alkylated products. The action of diazomethane on 5-nitro (I) and 6-nitro-indazole (IV) was investigated. Reduction of nitroindazoles with hydrogen on Pd/charcoal proceeds smoothly. The synthesis of several new benzimidazole and indazole dye intermediates is also described.

Notes: Two new macrocyclic alkaloids oncinotine (1) and isooncinotine (2) have been isolated from Oncinotis nitida BENTH. 1 can be converted into 2 by an amide exchange reaction. The spermidine residue was present in both bases. The structural elucidation was based mainly on (I) the determination of the functional groups, (II) degradation to compounds 12 and 13 and (III) mass spectrometric investigation of 1 and of the above mentioned degradation products.

Notes: Indantrion (1) bildet mit Trialkylphosphiten 2:1-Addukte, vermutlich cyclische Pentaoxyphosphorane 5. Aus 5c entsteht mit Säuren das bekannte Phosphat 2c. Triphenylphosphin reagiert mit 1 zum Ylid 10, dessen C=P-Bindung mit elementarem Schwefel gespalten werden kann. Aus p-Thiokresol bzw. Diphenyldithiophosphinsäure und 1 entstehen 1:1-Addukte, die nach ihren Spektren und chemischen Eigenschaften mit der Struktur 9b, c im Einklang sind. - 2-Benzyliden-indandion-(1.3) (11) addiert 1 Mol Diphenyldithiophosphinsäure zu Verbindung 12, deren Struktur spektral gesichert ist.
