An Efficient Synthesis of Functionalized 2-Oxoindole Derivatives by Organocatalytic Z/E-Selective Benzylic Functionalization of (o-Aminobenzyl)indoles with Isatins

Abstract: An efficient method has been established for the synthesis of functionalized 2-oxoindole derivatives through chemospecific benzylic functionalization of (o-aminobenzyl)indoles with isatins. This protocol not only provides ready access to functionalized 2-oxoindole derivatives in high yields (≤97%) and excellent Z/E-selectivities (Z/E > 95:5), but also serves as a good example of catalytic benzylic functionalization of (o-aminobenzyl)indoles.

On the Current Condition and Development of Conservation of Energy Both in China and Abroad

Abstract: Energy problem concerns the very existence of human beings, while conservation of energy in the construction field can be the most efficient and economical part in energy saving. Presently, the energy consumption in the field of construction constitutes 30-50% of the total social consumption in developed countries. And in China the construction field occupies 30% of the total social energy consumption. Hence, energy conservation in the construction field is of great importance in the development of energy. This paper also points out that energy conservation brings new developmental opportunities to the field of construction.

Expressions and perturbations for the Moore--Penrose inverse of bounded linear operators in Hilbert spaces

Abstract: Let $A,X,Y$ be bounded linear operators. In this paper, we present the explicit expression for the Moore--Penrose inverse of $A-XY$. In virtue of the expression of $(A+X)^\dag$, we get the upper bounds of $\|(A+X)^\dag\|$ and $\|(A+X)^\dag-A^\dag\|$.
