  Several new organomettalic isoxazoles, silylated and stannylated in the heterocyclic ring or in a side chain have been made. Their 13C NMR spectra are consistent with the previous conclusions on the electronic effects of MR3 and CH2MR3 (M = Si, Sn) groups, and indicate the importance of the pπ-dπ and σ-π mechanisms in the various ring positions.

  The Peterson reaction between a series of 2-substituted 1-azabicyclo[2.2.2]octan-3-ones and 3-methyl-5-trimethylsilanylmethyl isoxazole (1) was explored. (Z)-Stereoselectivity was obtained with all 2-substituents, ranging from 65:35 for benzyl to 95:5 for phenylsulphanyl. Different bases were investigated, revealing that an organolithium base is necessary for the reaction to occur. A transition state
