Abstract
Spiro compounds being multi-cyclic systems linked by a single atom, have distinct three
dimensionalities, and prominently hold a position of interest in the fields of synthetic and medicinal
chemistry, pharmacology, material sciences and physics. Spirobarbiturate compounds which incorporate
barbituric ring derivatives into spirocyclic structures have emerged as attractive synthetic targets
for drug discovery as they are known to exhibit far-ranging pharmacological applications. In this review,
we aim to bring to light the extensive, contemporary research applied to the synthesis of different
spirobarbiturates having varied ring sizes (3, 5, 6 and 7 membered) in a classified manner. It presents
the reported methods of synthesis along with their mechanistic pathways as well as the pharmacological
activities of some of these synthesized biologically significant motifs.
Keywords:
Spirobarbiturates, multi-component reactions, green synthesis, pharmacological applications, one-pot domino reactions, GABA receptors.
