Stack, Jeffrey G. published the artcileA new chiral auxiliary for asymmetric thermal reactions: high stereocontrol in radical addition, allylation, and annulation reactions, Formula: C8H16O2, the publication is Journal of the American Chemical Society (1992), 114(18), 7007-18, database is CAplus.
A new imide chiral auxiliary, endo-7-(2-benzoxazolyl)-1,5,7-trimethyl-3-azabicyclo[3.3.1]nonan-2-one (I), is prepared from Kemp’s triacid and resolved via its menthyl carbamate. Mixed fumarate derivatives of the auxiliary show unprecedented control of regiochem. and β-stereochem. in representative radical addition reactions. Chiral radicals derived from I also show extremely high levels of stereoselectivity in representative radical allylation and cyclization reactions. Structural features of the chiral auxiliary and features of radical addition are integrated into a model for stereoselection.
