cis,cis,cis,cis-1,2,3,4,5-Pentakis(hydroxymethyl)cyclopentane
Tetrahedron, 2013All-cis pentamethanolcyclopentane has been obtained in six steps by Diels–Alder condensation of maleic anhydride with (benzyloxymethyl)cyclopenta-2,4-diene, reduction of the anhydride to a diol that was protected as the acetonide. Then, ozonolysis of the double bond, followed by reduction led to a cis-diol.

Enantioselective syntheses of cis, syn, cis- and cis, anti, cis-linear triquinanes
Tetrahedron: Asymmetry, 2008Enantioselective syntheses of both cis, syn, cis- and cis, anti, cis-linear triquinanes, starting from the readily available (S)-campholenaldehyde, employing an RCM reaction-based cyclopentannulation strategy, are described.

All-cis-retinal and 7-cis,9-cis,11-cis-retinal1
Tetrahedron Letters, 1988Abstract A modified 15 + 5 route led to 7- cis ,9- cis ,11- cis -retinonitrile in high selectivity and also a lesser amount of all- cis -retinonitrile. DIBAL reduction gave the corresponding retinal isomers. The absorption maximum 287nm of all- cis -retinal reveals the distorted nature of the chromophore.
