Barluenga reagent
웹The reaction of tert-butylalkynyl chromium Fischer carbene complex 1 with nitrones 2 affords β-enamino-ketoaldehydes 4 by the light-promoted rearrangement of the corresponding [3+2] cycloadduct carbene complexes 3. On the other hand, [3+2] cycloaddition of chiral nonracemic Fischer alkenyl carbene complexes 19 with nitrilimines 10 yields enantiomerically pure Δ2 … 웹reagent can be employed to achieve similar goals such as elec-trophilic additions. The nitrate is often superior to its relatives (due to its higher electrophilicity) and may exhibit some vari-ations in reactivity. 4. Thus, for instance ...
