alkyl trifluoro(organylsulfonylimino)propionates with phosphites occurs with NC transfer of the RSO2 group and leads to sulfonyl-substituted trifluoroalanine derivatives. The novel rearrangement is interpreted as cheletropic 1,4-cycloaddition of the phosphite and subsequent 1,2-shift of the sulfonyl group in the intermediate cyclic phosphorane.

yields. Z stereoselectivity of the created alkenyl group is obtained with N2CHSiMe3, whereas N2CHCO2Et favours selectively the E configuration for the same doublebond. The diastereoselectivity exo/endo depends on the size of the created ring. The X‐ray structures of two products have been determined, showing the stereochemistry of the compounds. The reaction can be understood by initial [2+2] addition
