The photoamination of 1-(2-methyl-1-propenyl)naphthalene (1a) with ammonia in the presence of p-dicyanobenzene (p-DCB) occurred selectively at the alkenyl group but not at the naphthyl group to giv...
A series of optically active pyrano[3,2-c]chromenes have been synthesized through an asymmetric domino reaction of 4-hydroxy-2H-chromen-2-ones with malononitriles. The targeted molecules were obtained in excellent yields and enantioselectivities (up to 94% yield, 99% ee). The AChE inhibitory activity studies revealed that compounds 4n (IC50 = 21.3 μM) and 4p (IC50 = 19.2 μM) displayed potent acetylcholinesterase
通过4-羟基-2 H-苯甲基-2-酮与丙二腈的不对称多米诺反应,合成了一系列旋光的吡喃并[3,2- c ]色烯。以优异的收率和对映选择性(高达94%的收率,99%ee)获得了目标分子。AChE抑制活性研究表明,化合物4n(IC 50 = 21.3μM)和4p(IC 50 = 19.2μM)显示出有效的乙酰胆碱酯酶抑制作用。在大多数情况下,S-对映异构体优于相应的R-对映体。此外,分子建模为理解这类化合物对AChE的对映选择性提供了一种实用的方法。

The objective of this invention is to provide fluorescent compounds comprising a naphthalene skeleton, an electron donating group substituted at the 2- or 1-position of the naphthalene skeleton, and an electron attractive group substituted at the 6- or 4-position of the skeleton. The fluorescent compound of this invention is capable of emitting visible light having a desired color by choosing an appropriate combination of the electron donating group A, which has an electron-pushing function, and the electron attractive group B, which has an electron-pulling function.
