The 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 o
First highly regio- and diastereoselective synthesis of δ2-pyrazolines by [3+2] cycloaddition of chiral nonracemic Fischer carbene complexes with nitrilimines

[3+2] Cycloaddition of Fischer carbene complexes with nitrilimines is described for the first time. The 'onepot' conversion of Fischer carbenes into enantiomerically pure Δ2-pyrazolines with high regio-and diastereoselectivity is presented as a
