Paragraph 0056; 0062-0065, (2020/08/09)
The invention relates to an organic fluorescent molecular cage compound and a preparation method thereof. The organic fluorescent molecular cage compound is prepared by reaction of a polyaldehyde arylcompound and a polyamino aryl compound. The technical problem of on-site separation and recognition of nitro aromatic compounds is solved by quickly preparing industrially produced organic fluorescent molecular cage materials. The preparation process is simple and controllable, the reaction can be performed at room temperature, a catalyst and sample pretreatment are not needed, and the prepared organic fluorescent molecular cage has remarkable specific response to nitro aromatic compounds.
A cascade Aza-Cope/Aza-prins cyclization leading to piperidine derivatives

The cascade aza-Cope/aza-Prins cyclization of homoallylamines to give substituted piperidines has been explored. The use of glyoxalic acid as the carbonyl component afforded bicyclic structures as a result of the internal carboxylate anion trapping the intermediate cation. The unimolecular bis-, tris-, and tetrakis(homoallylamine)s efficiently delivered the appended bis-, tris- and tetrakis(piperidine-4-ol)s (tripod and crucifix shape, respectively) as new entities. The latter compound served as an excellent ligand in the Suzuki-Miyaura cross-coupling reaction to synthesize incrustoporin. The cascade aza-Cope/aza-Prins cyclization of homoallylamines to give substituted piperidines is described. A unimolecular tetrapiperidine derivative, which resulted from this strategy, was employed as a ligand in the Suzuki-Miyaura cross-coupling reaction of an α-iodobutenolide with an arylboronic acid in an efficient synthesis of incrustoporin and its analogues.
