TL;DR: The macrocyclic polyethers, (7) and (8), were synthesised stereospecifically from the diastereoisomeric acyclic methylene acetals, (1, and (2), obtained from (±)-cyclohexane-trans-1,2-diol as discussed by the authors.
Abstract: The macrocyclic polyethers, (7) and (8), have been synthesised stereospecifically from the diastereoisomeric acyclic methylene acetals, (1) and (2), obtained from (±)-cyclohexane-trans-1,2-diol; both (7) and (8) form stable complexes with metal cations.

TL;DR: A macrobicyclic polyether (4) was synthesised from pentaerythritol in four steps and is a suitable precursor to related compounds where the nature of the functional groups attached to the bridgehead carbon atoms can be varied as discussed by the authors.

TL;DR: In this article, the authors show that the cis-isomer is thermodynamically more stable than the transisomer in all cases, and that the latter is more stable when compared to the former.
Abstract: Equilibration studies on seven 2,4-disubstituted-γ-butyrolactones indicate that the cis-isomer is thermodynamically more stable than the trans-isomer in all cases.

TL;DR: The equilibrium proportions of the constitutional isomers and conformational behaviour of the cis-fused 1,3,6,8-tetraoxabicyclo[5, 3,0]decanes provide no evidence for the gauche arrangement of the vicinal oxygen substituents being a stabilising feature in these systems as mentioned in this paper.
Abstract: The equilibrium proportions of the constitutional isomers (1)–(4) and the conformational behaviour of the cis-fused 1,3,6,8-tetraoxabicyclo[5,3,0]decanes (1a)–(4a) provide no evidence for the gauche arrangement of the vicinal oxygen substituents being a stabilising feature in these systems.
