Methods were developed for the resolution of several five- and six-membered phosphorus heterocycles (1c-e, 2, 4). It was investigated if the optical activity is preserved during the 1a→2→3→4 reaction sequence. Racemic and optically active 1b-e 3-phosphole

Reaction of 6,6-dichloro-1-methyl-3-phosphinbicyclohexane 1-oxides 1 with silver nitrate in alkohols or water leads to the regioisomers of alkoxy- or hydroxy-1,2,3,6,tetrahydrophosphorin 1-oxides 2A and 2B or 3A and 3B.Each isomer consists of diastereoisomers.Water elimination from the hydroxy derivatives 3 results in the formation of the regioisomers of 1,2-dihydrophosphorin 1-oxides 4A and 4B.Constitution and strereostructure of the compounds has been elucidated by 1H, 13C, and 31P NMR spectroscopy.
