Abstract

Abstract The efficient synthesis of four benzyl 2-(S)-[(tert-butoxycarbonyl) amino]-ω- iodoalkanoates {benzyl 2-(S)-[(tert-butoxycarbonyl) amino]-3-iodopropanoate, benzyl 2-(S)- [(tert-butoxycarbonyl) amino]-4-iodobutanoate, benzyl 2-(S)-[(tert-butoxycarbonyl) amino]-5- iodopentanoate, benzyl 2-(S)-[(tert-butoxycarbonyl) amino]-6-iodohexanoate} from natural or protected l-amino acids is described.
