Microwave-assisted Regioselective 1-O-Deacylation of Peracylated Glycopyranoses on Alumina

A facile, rapid and regioselective method for the 1-O-deacylation of peracylated glycopyranoses is described which occurs under mild conditions by absorption onto alumina using microwave irradiation.     

Crystal Structure of Adduct 2-Phenyl-imidazo [ 4,5-f ] 1,10-phenanthroline Methanol

The structure of the title adduct comprises a phenanthroline derivative 2-phenyl-imidazo[4,5-f]1,10-phenanthroline and a methanol.The composition of the crystalline adduct was characterized as C19H12N4.CH3OH.It belongs to orthorhombic system,space group Pna21 with a=1.3693(4)nm,b=2.2988(7)nm,c=0.51338(15)nm,V=1.6160(8)nm^3.Z=4,and final R1=0.0423.wR2=0.1012 .Crystal structure shows that all the 19 carbon atoms and 4 nitrogen atoms are coplanar.The bond length data indicated that a very extensive conjugation system was formed.This conjugation makes the compound being a potentially excellent energy transformer used for luminescent materials.

EXISTENCE AND UNIQUENESS OF THE SOLUTION FOR NONLINEAR THIRD-ORDER ROBIN BOUNDARY VALUE PROBLEM WITH A TURNING POINT

The paper aims to obtain existence and uniqueness of the solution as well as asymptotic estimate of the solution for singularly perturbed nonlinear third- order Robin boundary value problem with a turning point.In order to achieve this aim,existence and uniqueness of the solution for third-order nonlinear Robin boundary value problem is derived first based on the upper and lower solutions method under relatively weaker conditions.In this manner,the goal of this paper is gained by applying the existence and uniqueness results mentioned above.     

佩尔蒂埃（Pelletier，Pierre Joseph，1788-1842）法国化学家（Chemist，France）

佩尔蒂埃是巴黎药物学校教授。1820年佩尔蒂埃和化学家卡旺图一起分离了番木鳖碱、辛可宁、奎宁和马钱子碱等有机碱。它们在动物体内起着很大的作用。马让迪后来把其中的几种用到医药方面。这就标志着药物学从浸泡和萃取转到使用已知的纯化学物——首先是自然生成物，然后是人工合成品。早在1817年，佩尔蒂埃和卡旺图分离出了一种植物性物质，这种物质没有明显的药物价值，但对生命体系却有无限巨大的价值，这是一种绿色化合物，由于它，植物才呈现绿色。
