TL;DR: In this paper, the cyclobutene ring opening reaction for the synthesis of double-stranded molecules is described and the synthesis and ring-opening reactions of the compounds endo-5a-e and 9a-c are described.
Abstract: Cyclobutene Ring Opening: A Useful Reaction for the Synthesis of Double-Stranded Molecules
Syntheses and ring-opening reactions of the compounds endo-5a – e and 9a – c, all containing cyclobutene rings, are described. From these experiments it is concluded that compound 9a is a useful AB-type Diels-Alder monomer for the synthesis of well-defined double-stranded molecules. The stereochemistry of the adducts endo-4b and endo-5d is determined by X-ray structure analysis.

TL;DR: In this article, the authors describe a route to obtain soluble, fully characterizable and high-molecular-weight ladder polymers with perfect molecular structures based on Poly-Diels-Alder -additions of suitable bifunctional building blocks.
Abstract: This paper describes a recently developed route to obtain soluble, fully characterizable and high-molecular-weight ladder polymers with perfect molecular structures. It is based on Poly-Diels-Alder -Additions of suitable bifunctional building blocks.
