A pillar[5]arene with an amino-terminated arm stabilizes the formation of aliphatic hemiaminals and imines

Chem Commun (Camb). 2019 May 14;55(40):5736-5739. doi: 10.1039/c9cc01947b.

Abstract

We report a new mono-armed pillar[5]arene with the amino-substituent self-included in the pillarene cavity, which can stabilize the hemiaminals and imines formed from the reaction of aliphatic amines and aldehydes as monitored by mass spectroscopy.
