Synthesis of Bicyclic Cyclopentanols by Photoreductive Cyclization of δ,ε-Unsaturated Ketones
Belotti, D.,Cossy, J.,Pete, J. P.,Portella, C.
, p. 4196 - 4200 (1986)
Bicyclic cyclopentanols were synthesized by intramolecular radical addition from photochemically induced electron transfer to δ,ε-unsaturated ketones.The donor was HMPA (neat) or Et3N (in CH3CN).Irradiation of δ,ε-ethylenic ketones and β-keto esters in HM
Alkyl radical generation by reduction of a ketone tosylhydrazone
Taber,Wang,Stachel
, p. 6209 - 6210 (1993)
Reduction of the tosylhydrazone of ketone 2 with NaBH3CN/ZnCl2 leads to a 3.5:1 mixture of 3 and 4. It is suggested that this reaction proceeds by radical chain decomposition of an intermediate monoalkyl diazene.

The Pt-catalyzed hydrosilylation of equilibrating allylic azides is reported. The reaction provides only one out of four possible hydrosilylation products in good yields and with very high chemoselectivity (alk-1-enevs.alk-2-ene), regioselectivity (linearvs.branched), and excellent functional group tolerance.

Fluoride-catalyzed stereoselective nucleophilic addition of PhSCF 2SiMe3 (1) to α-carboethoxycycloalkanones 2 followed by intramolecular radical cyclization of the resulting cis-3 adduct afforded the corresponding gem-difluoromethyle
Convenient access to bicyclic and tricyclic diazenes
Taber, Douglass F.,Guo, Pengfei
supporting information; experimental part, p. 9479 - 9481 (2009/04/06)
(Chemical Equation Presented) Heating the tosylhydrazone of an ω-alkenyl ketone or aldehyde to reflux in toluene in the presence of K2CO3 delivered the bicyclic diazene. Irradiation of the diazene converted it to the cyclopropane. Th
Stereochimie des hydroxy-5 methyl-4 bicyclooctanecarboxylates de methyle et des hydroxy-5 methyl-4 bicyclononanecarboxylates d'ethyle
Cossy, J.,Bouquant, J.,Dauphin, G.,Belotti, D.
, p. 879 - 883 (2007/10/02)
A spectroscopic study IR, 1H NMR, 13C NMR of methyl 5-hydroxy-4-methyl-bicyclooctanecarbocylates and of ethyl 5-hydroxy-4-methyl-bicyclononanecarboxylates and conformational calculations have permitted to determine the
