3-Phenyl- and 3-unsubstituted-2-alkenoyl-1-methylaziridines have been synthesized via Grignard reactions with the corresponding 2-cyanoaziridines.The 3-phenylated-2-alkenoylaziridines have been thermally transformed into ring-fused pyrrolidine compounds.The configurations and conformations of the aziridine and pyrrolidine compounds have been determined by 1H and 13C NMR spectroscopy and X-ray crystallography.
Reaction of Hydrogen Fluoride in Pyridine Solution with cis-Cyano-2- and cis-Amido-2-aziridines. Preparation of β-Fluoro-α-amino Acids and Esters by Means of Acidic Hydrolysis and Alcoholysis of β-Fluoro-α-Amino Nitriles and/or β-Fluoro-α-Amino Acid Amide

The addition of hydrogen fluoride generated from pyridinium poly(hydrogen fluoride) (i.e.Olah's reagent) to some cis-2-cyano- and cis-2-amido-aziridines has been examined.The reaction led to fluoroamine derivatives which upon acidic hydrolysis and alcohol

Nitrones, 5,5-dimethyl-Δ1-pyrroline N-oxide (5), and 3,4-dihydroisoquinoline N-oxide (6) were reacted with the five-membered cyclic phosphonates 2--2-oxo-4,5-dimethyl-1,3,2-dioxaphospholane (1) and 2-(cyanomethyl)-2-oxo-4,5-dimethyl-1,3,2-dioxaphospholane (2) and with the six-membered cyclic phosphonates 2--2-oxo-5,5-dimethyl-1,3,2-dioxaphosphorinane (3) and 2-(cyanomethyl)-2-oxo-5,5-dimethyl-1,3,2-dioxaphosphorinane (4).The reactions of the five-membered phosphonates gave aziridines as products, except that of 6 and 2.The reactions of the six-membered phosphonates gave exclusively or predominantly enamines.The reactions of C-phenyl-N-methylnitrone (7) with 2 gave only trans-1-methyl-2-cyano-3-phenylaziridine (22).Cyclic phosphates 2-hydroxy-2-oxo-4,5-dimethyl-1,3,2-dioxaphospholane (20) and 2-hydroxy-2-oxo-5,5-dimethyl-1,3,2-dioxaphosphorinane (21) were isolated as byproducts from the reactions of the corresponding phosphonates.
