The Ti(IV) enolates derived from α-diazo-β-keto esters or ketones efficiently add to TiCl4-activated N-tosylimines to give δ-N-tosylamino substituted α-diazo-β-keto carbonyl compounds. The diazo decomposition of the addition products occurs und

(N-Tosyl)amino substituted β-keto diazo carbonyl compounds have been prepared by reaction of titanium enolate of β-ketodiazoester or -ketone with an activated N-tosylimine. Rh2(OAc)4-catalyzed reaction of the (N-tosyl)amino substitut
Condensation of Conjugated Enones With Diethyl Aminomalonate: A New and Convenient Access to 2,2-Bis(ethoxycarbonyl)-3,4-dihydro-2H-pyrroles

2,2-Bis-(ethoxycarbonyl)-3,4-dihydro-2H-pyrroles are prepared from conjugated enones and diethyl aminomalonate by a one-step cyclocondensation reaction.Reduction of the products with sodium cyanoborohydride affords the corresponding pyrrolidines.
