  • An efficient three component synthesis of novel spiropyrrolidine compounds were obtained in good-to-excellent yields from the chemo-regio-and stereoselective reaction between �,�-unsaturated ketones with thiophene substituents and non-stabilized azomethineylides, generated in situ from acenaphthenequinone and sarcosine. This protocol has the advantages of highly efficiency, mild reaction conditions, a one-pot procedure, easy workup, short reaction times, convenient operation, and catalyst-free… CONTINUE READING
