A facile synthesis of N-aryl aziridines

Reaction of N-aryl-β-amino alcohols with p-toluenesulphonyl chloride under phase transfer catalytic condition gave the corresponding N-aryl aziridines in good yields, whereas N-alkyl-β-amino alcohol [for e.g., L-ephedrine] gave the corresponding N-tosyl derivative as the major product, along with the expected N-alkyl aziridines in lower yield.

Reactions of Spiro

Methylenefluorene 3a adds regiospecifically to aryl azides 4 to give the corresponding spiro 5, which lead to the ring-enlargement products, 9-(arylamino)phenanthrenes (9), by pyrolysis and acid-induced reaction.Benzylidenefluorene 3b
