Rhodium-catalysed hydroformylation and carbonylation of N-alkenyl-1,3-diaminopropanes
摘要:
The rhodium catalysed reactions of N-alkenyl-1,3-diaminopropanes with H-2/CO usually give mixtures of diazabicycloalkanes and aminopropyl lactams. The chemo-and regioselectivity of these reactions are influenced by the choice of ligand and by the ratio of H-2 and CO in the gas mixture and in some cases formation of a single compound can be achieved.

The invention provides a novel wrinkle-improving agent that has an effect of improving wrinkles, that does not entail problems of safety or pain even when applied to the skin, and that contains a very safe substance as an active component. A discovery was made that N-benzoyl-β-alanine, other specific β-alanine derivatives, and salts thereof have a wrinkle-improving effect, whereby a wrinkle-improving agent containing as an active component one, two, or more types of compounds selected from the group composed of these specific β-alanine derivatives and the salts thereof was developed.
Compounds of a certain formula I, in which Ra, Rb and Rc have the meanings indicated in the description, are effective compounds with anti-proliferative and/or apoptosis inducing activity.

The present invention is directed to a hair colouring method by using a composition and to said composition comprising a specified ring-fused heterocycle direct dyestuff having the general formula (1) or a salt thereof wherein the formulas are as defined in the patent claims.
Furthermore, the present invention is also directed to the composition. This composition has a surprisingly good hair colouring performance and compatibility with peroxides. The use of this composition leads to long lasting brilliant colours wherein the colour is stable against washing of the hair and environmental influences.
