✦ Synopsis

A facile synthesis of sprio{1-azabicyclo- [3,3,0]-6-octene-8,1 -phenanthrene}-2 -ones has been accomplished by [3 + 2] cycloaddition of azomethine ylide (amy) generated from 9,10phenanthrenequinone and different secondary cyclic amino acids, namely, thiazolidine-4-carboxylic acid, L-pyrrolidine-2-carboxylic acid (L-proline), and piperidine-2-carboxylic acid (pipecolinic acid) with electron-deficient dipolarophiles in 67%-79% yield. AM1 calculations have been performed to understand the stereochemical course of the cycloaddition. The products have been characterized by elemental analyses and spectroscopic techniques, namely IR, 1 H NMR, and 13 C NMR spectroscopies as well as mass spectrometry. Some of the synthesized cycloadducts showed moderate antioxidant activity.
