B. Alcaide et al., THE ASYMMETRIC-SYNTHESIS OF 2,3-BENZOCARBAPENEMS BY INTRAMOLECULAR ARYL RADICAL CYCLIZATIONS, Tetrahedron : asymmetry, 7(8), 1996, pp. 2203-2206
Racemic and enantiomerically pure 2,3-benzocarbapenems 1 are obtained
in good yields by the tin-mediated, intramolecular aryl radical cycliz
ations of the readily available 4-alkenyl-N-(2-halogenophenyl)-beta-la
