worin Ar 1 einen unsubstltuierten oder substituierten aromatischen Rest bedeutet und mindestens einer der Reste R 1 und R 2 eine Alkenyl-, Cycloalkenyl- oder Arylmethylgruppe bedeutet, sind wirkungsvolle Photoinitiatoren für die Photopolymerlsation ungesättigter Verbindungen. Sie eignen sich Insbesondere zur Photohärtung pigmentierter Systeme.
摘要:
This invention relates to a method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene. The ligands comprise a class of ketones.
摘要:
The invention relates to the field of organic chemistry and particularly to a process for the synthesis of alpha-amino nitriles which comprises subjecting an RCN nitrile to the action of a metal reducing agent to form a metal imine, and treating the latter with a cyaniding agent in order to obtain a compound of formula (I). The compounds of formula (I) are valuable synthesis intermediates, particularly for the production of natural or synthetic amino-acids.
