The Sensitivity of Structure to Ionic Radius and Reaction Stoichiometry: A Crystallographic Study of Metal Coordination and Hydrogen Bonding in Barbiturate Complexes of All Five Alkali Metals Li–Cs

Molecules
A systematic study has been conducted on barbiturate complexes of all five alkali metals, Li–Cs, prepared from metal carbonates or hydroxides in an aqueous solution without other potential ligands present, varying the stoichiometric ratio of metal ion to

Enantioselective Synthesis of Spirobarbiturate-Cyclohexenes through Phosphine-Catalyzed Asymmetric [4 + 2] Annulation of Barbiturate-Derived Alkenes with Allenoates

, 2016
An enantioselective synthesis of pharmaceutically important spirobarbiturates has been achieved via spirocyclic chiral phosphine-catalyzed asymmetric [4 + 2] annulation of barbiturate-derived alkenes with allenoates.

A study of barbiturate intoxication by an ultra-violet spectrophotometric technique

, 1953
The diagnosis of barbiturate intoxication is usually made from circumstantial evidence coupled with a characteristic, if non-specific, clinical picture. The need for a confirmatory laboratory test is often felt. Riley, Krause, Steadman, Hunter, and Hodge

Interlocked structures based on H-bonded barbiturate complexes

, 2015
The work contained within this thesis concerns the synthesis and characterisation of novel [2]-rotaxanes, mediated via H-bonded templation. The template in question is based upon the barbiturate receptor as developed by A. D.
