ChemInform Abstract: Cyclic Nitronates from the Diastereoselective Addition of 1‐Trimethylsilyloxycyclohexene to Nitroolefins. Starting Materials for Stereoselective Henry Reactions and 1,3‐Dipolar Cycloadditions.

Abstract The Ti‐induced combination of the cyclohexene (I) with the E‐nitroolefins (II) yielding the separable prim. products (III)‐(V) proceeds preferentially with relative topicity ul, opposite to the corresponding reaction of enolates or enamines.
