An increasing number of examples of ring formation through 1,5-electrocyclization of appropriate carbanions are illustrated in Scheme 27. In the last example the use of a chiral alkoxide (R = menthyl or bornyl) results in the formation of chiral indolines with optical purities ranging from 17 to 31%.

Koizumi and co-workers used the optically active allylic chloroselenuranes bearing the 2-exo-hydroxyl-10-bornyl group to obtain optically active allylic amines [41]. The treatment of allylic selenides with f-BuOCl gave the corresponding allylic chloroselenuranes as the only product. Benzyl carbamate, t-butyl carbamate, p-tosylamide, and diphenylphosphinamide were selected as the AT-protected amines for selenimide formation. The nucleophilic reaction of... 

Subsequently, chiral terpyridines bearing bornyl substituents in their 6-positions (73 and 74) have been employed for copper(I) helicate formation.The two enantiomeric forms of the ligand preferentially form dinuclear double helicates with P and M chiralities, respectively. Both chiral isomers have been characterised structurally by X-ray diffraction. 

A polar-type transition state is also supported by the occurrence of Wagner-Meer-wein rearrangements accompanying the elimination of hydrogen chloride, from neo-pentyl - " - - , bornyl > andisobornylchlorides - ° In the case of neopentyl chloride the formation of 2-methylbut-l-ene and 2-methyl-but-2-ene has been explained in terms of a non-classical carbonium ion type transition state. 

For the reduction of 1,4-dihalonorbornanes at platinum in DMF containing TEABr, Wiberg and coworkers [159] found that the products are norbornane and l,l -binorbornyl, but there was no evidence for the formation of [2.2.1]propellane. However, when 1,4-dihalonorbornanes are electrolyzed at mercury in DMF [169,170], the major products are norbornane and bis(l-norbornyl)mercury, along with a small amount of l,l -binor-bornyl, and it was concluded that [2.2.1]propellane is an intermediate. 

Winstein proposed that the much faster rate for the solvolysis of the exo-nor-bornyl brosylate (11) was the result of participation by the 1,6-bonding pair in the transition state, leading to the formation of a a-bridged (nonclassical) cation intermediate (15) (7). The nonclassical cation 15 possesses a plane of symmetry. Consequently, the acetate product, 12, must be optically inactive. 

Irradiation of electron deficient arenes in the presence of cis-l,2-diphenylcyclopropane leads to formation of the trans isomer by an electron transfer mechanism. The reaction occurs by way of the radical cation of the cyclopropane which isomerises prior to back electron transfer. It has now been examined using menthyl and bornyl esters of benzene tetracarboxylic acid as chiral electron transfer sensitisers. °° Slight excesses of one of the enantiomers of the trans-1,2-diphenylcyclopropane were observed. The dicyanoanthracene sensitised reactions of 1,1,2,3-tetra-arylcyclopropanes have been studied.Depending on the substituents present on the arene rings these compounds rearrange to 1,1,3,3-tetra-arylpropenes. The rearrangement occurs in a ring opened radical cation intermediate. 

Complexes of unsymmetrical dienes are chiraF, and the reaction stereospedficity results in formation of a new asymmetric center, fully resolved and of known absolute configuration relative to the precursor . This is useful in organic synthesis, since cations can be resolved through related neutral complexes such as bornyl ethers or carboxylic acids".
