Efficient Synthetic Method for ifferentially Protected Naturally Occuring Acylic Polyamides
Iwata, Masaaki,Kuzuhara, Hiroyoshi
, p. 1102 - 1106 (2007/10/02)
A new systematic route to threefold protected natural polyamides, spermidine, spermine, thermine, and thermospermine, was developed through alternate regioselective manipulation on the terminal primary amino groups, starting from N,N-phthaloyl-1,3-propane
