environment nearby the Pd metal center. Three rings of multilayer 3D products can be readily changed by varying aromatic ring-anchored starting materials. The resulting multilayer products displayed strong luminescence under UV irradiation and strong aggregation-induced emission (AIE). In the future, this work would benefit not only the field of asymmetric synthesis but also materials science, in particular
A trans or cis ethenyl group has been inserted between the α-carbon and the carboxyl group of α-aminoacids by Horner stereoselective olefination of α-aminoaldehydes. Numerous pure cis and trans vinylogous α-aminoacids have been obtained thus and coupled with aminopartners by classical methods. The versatility of the method was illustrated by the preparation of a [trans vinylogous-Gly3]Leu-enkephalin
