Recently I am researching about TRIMETHYLSILYL CYANIDE; ENANTIOSELECTIVE CYANOSILYLATION; PRACTICAL SYNTHESIS; AMINO-ACIDS; CYANATION; IMINES; PENTACOORDINATE; HYDROCYANATION; REACTIVITY; ALDIMINES, Saw an article supported by the JSPS KAKENHIMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of ScienceGrants-in-Aid for Scientific Research (KAKENHI) [JP17H03054, JP15H05755, JP15H05810]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Hatano, M; Nishio, K; Mochizuki, T; Nishikawa, K; Ishihara, K. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine. Quality Control of Diphenylmethanamine
An enantioselective Strecker-type reaction of aldimines and ketimines was developed by using a chiral dilithium(I) binaphthyldisulfonate as a chiral acid-base cooperative catalyst. The present catalytic system features an extremely short reaction time (10 min to 4 h), unlike conventional catalytic systems. Along with the design of stronger chiral Li(I) Lewis acid catalysts, a highly reactive pentacoordinate silicate generated in situ could promote the reactions. In particular, instead of unstable N-Bn Strecker products, more stable N-CH2 (9-anthryl) and N-CH2 (1-naphthyl) Strecker products could be obtained in high yields with high enantioselectivities. By a switch of the present and previous catalyst systems, chemoselective cyanation to a ketoaldimine could be performed, respectively. Moreover, mechanistic investigations provided useful information regarding the active catalysts, catalytic cycles, and possible transition states.
