Two isomeric pairs of compounds, cis-and trans-2morpholino-2-thiono-4-methyl-1,3,2-dioxaphosphinane (1A β«Χβ¬ 1B) and 2-morpholino-2-oxo-4-methyl-1,3,2-dioxaphosphinane (2A β«Χβ¬ 2B) were obtained and separated into the pure compounds by silica gel chromatography. Attempts at crystallization afforded 1A
The oxidative cyclization of the thiosemicarbazones of 4-piperidones (2) furnished spiro piperidino-1,2,4-triazoles (3,4,5), while the pyrolysis of 5 led to spiro piperidinoaziridines (6). The new compounds were characterized by IR and 1 H NMR spectral data.
