Reductive Aminations of Carbonyl Compounds with Borohydride and Borane Reducing Agents
Ellen W. Baxter,Allen B. Reitz +1 more
TL;DR: A review of reductive aminations using borohydride and borane reducing agents can be found in this article, where the authors focus on those conditions in which the carbonyl component, amine, and reducing reagent react in the same vessel.

Synthesis and characterization of poly(2,6-dimethyl-4-phenyl-1,4-dihydropyridinyl)arenes as novel multi-armed molecules
TL;DR: In this paper, a series of poly(2,6-dimethyl-4-phenyl-1,4-dihydropyridinyl)arenes were synthesized in good yields using a one-pot, acid-catalyzed cyclocondensation reaction of the appropriate poly(aldehydes) with 3-aminobut-2-enenitrile in acetic acid at reflux.

Synthesis of designed hetero-polytopic cryptands through Schiff base condensation
TL;DR: In this article, low-temperature synthesis of a number of hetero-polytopic cryptands has been achieved in good yields without employing any templating metal ion, and the cryptands are designed to hold more than one metal ion in its cavity.

TL;DR: The synthesis of a new macrobicyclic cryptand (L) with heteroditopic receptor sites has been achieved in good yields by the [1 + 1] Schiff base condensation of tris(2-aminoethyl)amine (tren) with the tripodal trialdehyde, tris{[2-(oxomethyl)phenyl)oxy]ethyl}amine at 5 degrees C temperature.
