• Spiro_compound abstract "A spiro compound is a bicyclic organic compound with rings connected through just one atom. The rings can be different in nature or identical. The connecting atom is also called the spiroatom, most often a quaternary carbon ("spiro carbon"). All spiro compounds have the infix spiro followed by square brackets containing the number of atoms in the smaller ring and the number of atoms in the larger ring excluding the spiroatom itself; the numbers being separated by a dot. For example compound A is called 1-bromo-3-chlorospiro[4.5]decan-7-ol and compound B is called 1-bromo-3-chlorospiro[3.6]decan-7-ol. The spiro compound consisting of a cyclohexane ring and a cyclopentane ring is called spiro[4.5]decane. This nomenclature was proposed by Adolf von Baeyer in 1900. An example of a spiro compound with a trivial name: spiropentadiene.Synthetic and natural spiro carbocycles attract attention of organic chemists owing to their unique structural features and numerous possible reactions in which they undergo carbon–carbon bond cleavage. For example, natural compounds such as fredericamycine, acorenone B, β-vetivone, ACAT-inhibitor, and isocomene isolated from plants contain spirocarbonatoms; the synthetic spirans include non-trivial compounds such as [5.5.5.5.]fenestrane, triangulanes, and [6.5]coronane. The properties of spiro carbocycles such as high reactivity are combined with fairly high thermal stability, and the existing synthetic difficulties usually faced by researchers when choosing the synthetic routes to target compounds stimulate many organic chemists to develop rational preparative approaches to various spiro carbocycles.There are quite a few published reviews, papers and patents that mainly present classical methods for the synthesis based on multistep synthetic strategies and expensive and exotic reagents.Meanwhile, the application of techniques of metal complex catalysis to organic and organometallic synthesis markedly facilitated the synthetic routes to spirans and made these syntheses promising for not only laboratory practice but also industry.During the last 10-15 years, considerable progress has been made, and a series of original methods and effective reagents for the preparation of various spiro carbocycles have been reported.Therefore, we attempted to give a critical account and general survey of the publications available from the literature on the synthesis of spirans using metal complex catalysts.".
