WebPseudolarolide Q Although there may not be as many well-known "general" methods for the construction of cyclopentanes as there are for 3,4, or 6 membered rings, there are in fact an enormous number of methods that have been applied to their synthesis, so this review is by no means comprehensive. WebViewing a Newman projections of cyclopentane sighting along one of the C-C bond show the staggered C-H bonds. Newman projection of cyclopentane The angle strain in the envelope conformation of cyclopentane is low. The ideal angle in a regular pentagon is about 107 o, very close to the preferred 109.5 o tetrahedral bond angle.
