标题:P(III)-亲核试剂银催化对醌甲基化物的区域选择性磷酸化
摘要:P(III)-亲核试剂 (P(Or) 3,Arp(Or) 2,Ar 2 P-Or)银催化对醌甲基化物 ( P-Qms )区域选择性磷酸化的简单有效方法通过 Michaelis-Arbuzov 型反应建立.在温和条件下,广泛的 P(III)-亲核试剂和对-醌甲基化物具有非常好的耐受性,从而得到预期的二芳基甲基取代的有机磷化合物,具有非常好的收率.此外,以二烷基芳基亚膦酸酯(Arp(Or) 2 )为底物,可以得到一系列相应的对映异构体.对照实验和31还进行了 P NMR 跟踪实验以深入了解可能的反应机制.该协议可能对michaelis-Arbuzov 型反应中 C( Sp 3 )-P 键的形成具有重要意义.

摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.
