“A Highly Efficient and Stereoselective Cycloaddition of Nitrones to N-Vinylpyrroles”
Synthesis, 2014, 46, 0771-0780
1,3-Dipolar cycloadditions of a number of C-aryl, C-carbamoyl-, and C,C-bis(methoxycarbonyl)nitrones and substituted N-vinylpyrroles proceed with high efficiency and regioselectivity with the formation of only one isomeric substituted 5-(1H-pyrrol-1-yl)isoxazolidine cycloadduct.

“Synthesis of indene derivatives via reactions of vinylidenecyclopropanes with the N-acyliminium cations generated from hydroxylactams”
Tetrahedron Lett., 2014, 55, 2022-2026
A novel route for the synthesis of 1H-indene derivatives via the reactions of vinylidenecyclopropanes (VCPs) with the N-acyliminium cations generated from hydroxylactams is described.
