Reaction of 3-alkenols with thallium trinitrate: An unexpected and useful ring contraction
Ferraz, Helena M. C.,Santos, Andrea P.,Silva Jr., Luiz F.,Vieira, Tiago De O.
, p. 751 - 762 (2000)
The first thallium trinitrate (TTN) mediated ring contraction of cyclic homoallylic alcohols, using a 1:1 mixture of AcOH and H2O as solvent, is described. The reaction of two of these alcohols with excess of TTN in pentane gave α-spirocyclopentyl-γ-butirolactones in reasonable yields.

Bertrand, Marcel,Meou, Alain,Tubul, Arlette
, p. 3691 - 3694 (2007/10/02)
The title reaction gives a mixture of four compounds .A 2-cyclohexyllideneoxetane is invoked as intermediary to account for the unusual lactone formation.
A New Spiro-annelation Procedure: Intramolecular Decarboxylative Alkylation of β-Keto-esters
Eilerman, Robert G.,Willis, Brian J.
, p. 30 - 32 (2007/10/02)
A new intramolecular decarboxylative alkylation route to spirocyclic ketones, and its application to the synthesis of (+/-)-β-vetivone and (+/-)-β-vetispirene are described.
