Functionalized phosphonium salts in Wittig reactions give ethylenic amines.With aldehydes the nature of the carbon chain and of the substituents on nitrogen have no influence on stereochemistry; ethylenic ketones, give aminopolyenes.Steroids give aminosteroids if a large excess of phosphonium salt is used.Amphiphilic compounds may therefore be prepared and aminoalkyl groups may be introduced to molecules with potential biological activities.
