  Regioselective Deprotection and Acylation of Penta-N-Protected Thermopentamine

  摘要：

  The synthesis of the penta-N-protected polyamide 1 (ten-butyl N-{9-allyl-16-azido-13-(trinuoroacetyl)-4-[2-(trimethylsilyl)ethylsulfonyl]-4,9,13-triazahexadecyl]carbamate = tert-butyl N-{3-{[4-{allyl[3-[(3-azidopropyl)(trifluoroacetyl)aminopropyl}amino}butyl}{[2-(trimethylsilyl)ethyl]sulfonyl}amino}propyl}carbamate) is described, a derivative of thermopentamine (PA 3433) containing five independently removable amino-protecting groups. The selective deprotection of the five protecting groups used, it., of allyl, azido, (tert-butoxy)carbonyl (Boc). trifluoroacetyl, and [2-(trimethylsilyl)ethyl]sulfonyl (SES), as well as the rapid transamidation reaction of the trifluoroacetyl group yielding secondary amides is discussed. Subsequent acylation with 4-methoxycinnamoyl chloride at each N-atom of the pentamine backbone is achieved. For the acylation of the terminal N-atom the azido group is replaced by a (2,2,2-trichloro-1,l-dimethylethoxy)carbonyl (Tcboc) group.
