DABCO-catalyzed reaction of allenic esters and ketones with salicyl N-tosylimines: synthesis of highly functionalized chromenes.

Yong-Ling Shi1, Min Shi.   

Abstract

[reaction: see text] DABCO-catalyzed reactions of salicyl N-tosylimines with ethyl 2,3-butadienoate and penta-3,4-dien-2-one proceed smoothly at room temperature in dichloromethane to give the corresponding chromenes in good to excellent yields.
