The oxygen atoms of the planar five-membered ring chelate axial and equatorial positions. In summary, we have reported for the first time a convenient method for the preparation of stable silaoxiranes Figure 3.

They are the omitted for clarity. They may serve Their formation proves that base stabili- zation allows isolation of silaoxiranes which are otherwise spirocyclic structure the Si atom is part of a four- and a three- assumed to exist only as intermediates.
The Si atom exhibits a distorted square- pyramidal geometry. The coordination sites of the Si atom are Received: February 10, occupied by the N atoms of the amidinato ligand and one Published online: April 15, oxygen and one carbon atom from the epoxide ring. The fifth coordination site is occupied by a chlorine atom.

Ando, T. Shiba, T. Hidaka, K. Description This current and five previous volumes Volumes , , , , convincingly demonstrate the vast applications of small rings in modern Organic Synthesis. Such applications range from total syntheses of cyclopropyl-group-containing natural products and non-natural biologically active compounds or compounds with other important properties via syntheses of cyclopropyl analogues to the use of cyclopropyl groups as reactive subunits.
This volume covers a survey of the wide range of biological activities of cyclopropyl-containing compounds, up-to-date comprehensive reviews on the multiple applicabilities of two multifunctional small ring building blocks - methyl 2-chlorocyclopropylideneacetate and bicyclopropylidene - in Organic Synthesis as well as a striking new approach to cyclopentenones from easily accessible 1-ethynylcyclopropanols, which is rather general and favorably complements other cyclopentenone syntheses.
