Abstract
A convenient multi-gram preparative method for the synthesis of linear oligoamines having the terminal primary amino groups unprotected and the central secondary amino functions protected with tert-butoxycarbonyl groups is presented. At the same time, simple one-pot preparation of the α,ω-bis(trifluoroacetamide) intermediates 2 has been developed. NMR spectra of the novel selectively protected oligoamines are also discussed.
