Abstract

Efficient Protocol for the Synthesis of Novel Spiro[acenaphthylene-1,2'-pyrrolidin]-2-one Compounds. -21 Title compounds are prepared by a catalyst-free 1,3-dipolar cycloaddition of azomethine ylides formed in situ from (I) and (III) with chalcones (II). The X-ray structure of (IVa) is given. -(LIN, Y.; FU, Z.; SHEN, T.; CHE, F.; SONG*, Q.; Synth. Commun. 45 (2015) 19, 2188-2194, http://dx.
