The synthesis and characterization of a series of N-Zn, N-Cu complexes with 2-amino pyridine and ethylenediamine ligands (1a–b and 2a–b) have been described. They were synthesized with a simple, one-pot method, and the crystal structures of 1a, 1b, 2a and 2b were determined by X-ray crystallography. The complexes were also characterized by NMR, IR, and elemental analysis. They were used as the catalysts in an application to the Henry reaction, and high yields were obtained under the optimum conditions.

Smart space refers to the integration of compute resources, information equipment and multi-modal sensing devices in the work or living space so that diverse services can be shared between different users in a smart way. Such a form of pervasive computing can not only make compute resources and information services universally available in such a way suitable for people's special uses but also bridge the digital information space and the physical world. However, given the properties of the smart space-each service with different resource requirements and goals, the smart space could cause resource conflicts in uses between different services and participants, and thus lead to the resource contention. In order to solve this problem while fulfilling the requirements of variable services in the smart space, in this paper, we leverage the concept of microservice to propose a universal resource scheduling and a process-evolution method for multiple concurrent services in the smart space. At the same time, to ensure that the microservice-based method is easy to implement, we also design a corresponding scheduling architecture based on the docker engine, which can functionally decompose application into a set of collaborative services. Finally, we carry out a experiment to show that the proposed architecture can achieve reasonable resource allocation, resolve resource contention, and exhibit the virtue of closed loop within different scenes and cross-scenario linkages.

Cyclic ketones react with (E)-2-nitroallylic acetates in the presence of catalytic pyrrolidine-thiourea, which affords bicyclic skeletons with four or five stereocenters in one single reaction with up to 98 % ee in moderate to high yields. The cooperative effects of both enamine and the Brønsted acid are found to be crucial for the high reactivity and enantioselectivity of this cascade reaction, which is demonstrated by both theoretical calculation and experimental data.
