An efficient regio- and diastereoselective cyclization of sulfamate-derived cyclic imines with unsubstituted or monosubstituted α-halo hydroxamates is developed under mild conditions. This reaction proceeds smoothly under transition-metal-free conditions via a domino aza-Mannich addition/intramolecular nucleophilic substitution sequence, providing a convenient route to access 2-monosubstituted and 2,5-disubstituted 4-imidazolidinones. Notably, the products were obtained with single trans-isomers in moderate to excellent yields.

A catalyst-free, base-mediated N- sec -alkylation of amides by reaction of sulfonylindoles and α-halohydroxamates has been developed. The N- sec -alkylation of amides reaction is based on an intermolecular nucleophilic addition of vinylogous imine with N
Synthesis of spirobarbiturate-pyrrolidinones: Via a domino aza-Michael/SN2 cyclization of barbiturate-derived alkenes with N-alkoxy α-haloamides

A highly efficient domino aza-MIRC (Michael Induced Ring Closure) reaction between barbiturate-derived alkenes and N-alkoxy α-haloamides has been achieved in moderate to excellent yields. This reaction proceeds smoothly under mild conditions via a domino aza-Michael addition/intramolecular SN2 sequence, providing a practical tool in the synthesis of bioactive molecules spirobarbiturate-3-pyrrolidinones.
