-
The cyclizations of L-(+)-prolinol 1 derived from L-proline with (thio) phosphoro(-no) dichlorides 2 give 1,2,3-azaphosphaoxabicyclo[3.3.0]octanes 3 consisting of unequal amounts of diastereoisomers,eight pairs of which have been successfully separated by silica gel column chromatography or recrystallization.
