## Abstract A series of 2βanilinoβ2βthioβ1,3,2βoxazaphospholanes derived from ephedrine has been synthesized and conformationally studied by proton NMR and Xβray crystallography. The NMR data can be interpreted in terms of twistβenvelope conformations in which the anilino substituents on phosphorus

β¦ Synopsis
Although reactions between (-)ephedrine E2-(S)-methylamino-l-(R)-phenylpropan-l-017 and RPOC12 (R = Cl, alkyl, aryl, alkoxy, aryloxy) can in principle afford pairs of 1,3,2-oxazaphospholanes eyimeric at phosphorus, most reports describe only one product from highly stereoselective reactions.

The cyclopropenyl anion is the simplest antiaromatic system. Evidence has been accumulated' that this anion is destabilized by conjugation and strain, and that most substituted derivatives are of very high energy indeed. However, a reasonable extrapolation of substituent effects to this system sugge
