Profound Catalyst Effects in the Generation and Reactivity of Carbenoid-Derived Cyclic Ylides
摘要:
In contrast to results with Rh-2(OAc)(4), good yields of ylide-derived [1,2]-shift (or in some cases [1,4]-shift) products were obtained upon treatment of amino diazo ketone substrates 3b,c and alkoxy diazo ketone substrates 5b,c with soluble Cu(II) catalysts.
