Amide α,β-Dehydrogenation Using Allyl-Palladium Catalysis and a Hindered Monodentate Anilide
摘要:
A practical and direct method for the alpha,beta-dehydrogenation of amides is reported using allyl-palladium catalysis. Critical to the success of this process was the synthesis and application of a novel lithium N-cyclohexyl anilide (LiCyan). The reaction conditions tolerate a wide variety of substrates, including those with acidic heteroatom nucleophiles.
Methods for the synthesis and use of functionalized, substituted naphthalenes are described. The functionalized, substituted naphthalenes display useful properties including liquid crystals and fluorescence properties, such as solvatochromatic fluorescence, with high quantum yields, Stoke's shift, and show emission maxima that are significantly red-shifted.
