Cycloaddition of (E)-N-[2-([2.2]paracyclophan-4-yl)ethylidene] methylamine-N-oxide with 2,3-diphenylcyclopropenones and dibenzoyl acetylene; synthesis of new paracyclophanylpyrroles

When N-[2-([2.2]paracyclophan-4-yl)ethylidene]methylamine-N-oxide (1) is treated with cyclopropenones 6a-c, the [2.2]paracyclophane-based pyrrole(-2-one, -thione and -ylidene malnonitrile) 7a-c are formed in good yields via formal [3π + 3π]cycloaddition. The reaction of 1 with dibenzoyl acetylene (12) afforded, via a Michael-type reaction, the stereoisomeric pyrrole 13. The reaction mechanism described the products formation is discussed.
