Gold catalysis for organic synthesis
The past decade has witnessed a remarkable growth in the number of organic reactions that are catalyzed by homogeneous gold complexes. Many of the early reported reactions took advantage of the propensity of gold complexes to serve as excellent catalysts for reactions that proceed through π-activation of carbon–carbon multiple bonds. Subsequently, the reactivity paradigms available for gold com...
متن کاملGold catalysis for organic synthesis II
Many of the early examples of homogeneous gold-catalysis focused on the ability of cationic gold complexes to activate π-bonds towards attack of nucleophiles. This reactivity platform, examples of which can be found in this Thematic Series, continues to provide a fruitful basis for the discovery of important new transformations. This includes the development of a tandem or domino process that c...
متن کاملpart a: application of n-(p-toluenesulfonyl) imidazole (tsim) and triphenylphosphine/carbon tetrachloride in several organic transformations part b: application of 8-bromocaffeine for synthesis of some novel 8-caffeinyl derivatives
بخش اول این پایان نامه به طور عمده بر توسعه کاربردهای جدید n-(پارا-تولوئن سولفونیل) ایمیدازول (tsim) و تری فنیل فسفین/ تتراکلرید کربن در تبدیل گروههای عاملی به یکدیگر استوار است. نظر به تنوع زیاد، دردسترس بودن، سمیت کمتر و نقل و انتقال آسان تر الکل ها نسبت به آلکیل هالیدها، تبدیل مستقیم گروه هیدروکسیل به گروه های عاملی دیگر مثل آزید، نیتریل و استر یکی از مهم ترین تبدیلات در سنتزهای آلی است. با ...

Palladium-catalyzed Heck-type reaction of oximes with allylic alcohols: synthesis of pyridines and azafluorenones.
We describe herein a palladium-catalyzed Heck-type reaction of O-acetyl ketoximes and allylic alcohols to synthesise pyridines. This protocol allows the robust synthesis of pyridines and azafluorenones in good to excellent yields with tolerance of various functional groups under mild conditions. The reaction is supposed to go through an oxidative addition of oximes to palladium(0) complexes, ge...
