Chiral [2.2.2] dienes as ligands for Rh(I) in conjugate additions of boronic acids to a wide range of acceptors
Defieber, Christian,Paquin, Jean-Francois,Serna, Sonia,Carreira, Erick M.
, p. 3873 - 3876 (2007/10/03)
We document a series of investigations that led to new substituted [2.2.2]-diene ligands which display high selectivity in Rh(I)-catalyzed conjugate addition reactions to substrates not previously examined with diene ligands. Moreover, we disclose an unexpected, interesting effect that results from the introduction of a third C=C onto the ligand scaffold (cf. 1).
Unusual stereochemical course of epoxide rearrangement in a carvone-derived series
Neef, Guenter,Baesler, Siegfried,Depke, Gisbert,Vierhufe, Harry
, p. 7969 - 7973 (2007/10/03)
Carvone-derived 2,3-epoxy alcohol derivatives rearrange with stereoselective formation of ring-contracted ketones. In contrast to previously described similar processes, the stereochemical result seems to be independent of epoxide configuration.
Radical cyclisation strategies to bridged systems. Regioselective construction of chiral bicyclo [2.2.2] and [3.2.1] octanes via 6-exo trig and 5-exo trig radical cyclisation reactions
Srikrishna,Hemmalini
, p. 9337 - 9354 (2007/10/02)
Radical cyclisation reaction of the bromoenones 6 and 7, obtained from (R)-phenyl carvone 3, gave a mixture of bicyclo [2.2.2] and [3.2.1] octanones via competitive 6-exo trig and 5-exo trig modes. On the other hand, radical cyclisation reaction of the al
Cyclopropanes via an Efficient 3-Exo Trig Radical Cyclisation Reaction
Srikrishna, Adusumilli,Sharma, G. Veera Raghava,Hemamalini, Parthasarathy
, p. 1681 - 1683 (2007/10/02)
The first examples of an exclusive formation of a cyclopropane via the 3-exo trig radical cyclisation of homoallyl bromides 13 and 14 are reported.
