  Synthesis of nonionic reduced-sugar based bola amphiphiles and gemini surfactants with an α,ω-diamino-(oxa)alkyl spacer

  摘要：

  Reduced-sugar based gemini surfactants with an alpha,omega-diamino-(oxa) alkyl spacer exhibit a rich pH-dependent aggregation behavior and are efficient DNA carriers in gene transfection. Herein, we describe an improved synthetic procedure for these amphiphiles. First, a series of novel nonionic bolaform amphiphiles with identical headgroups and alpha,omega-diamino-(oxa) alkyl spacers were synthesized by reductive aminations involving alpha,omega-diaminoalkanes and the appropriate sugars or aldehydes. The bolaform compounds were used as starting materials for the synthesis of the corresponding reduced-sugar based gemini surfactants in a reductive alkylation reaction employing a polymer-bound cyanoborohydride. A series of new gemini surfactants have been synthesized and characterized. (C) 2007 Elsevier Ltd. All rights reserved.

  A synthetic strategy for novel nonsymmetrical bola amphiphiles based on carbohydrates

  摘要：

  A number of novel nonionic bolaform amphiphiles with nonidentical aldityl head groups, 1-(1-deoxy-D-galactitol-l-ylamino)-6-(1-deoxy-D- galactitol-1-ylamino)hexane (4a), 1-(1-deoxy-D-mannitol-1-ylamino)-6-(1-deoxy-D-glucitol-1-ylamino)hexane (4b). and 1-(1-deoxy-D-tialactitol-1-ylamino)-6-(1-deoxy-D-Mannitol-1-ylamino)hexane (4c) were synthesized by two successive reductive aminations involving 1,6-diaminohexane (4) and the appropriate (1)-aldohexoses (D-glucose, D-mannose, and D-galactose) using 5% Pd on carbon as the catalyst. Typical reaction conditions were 40 degreesC, 4 MPa hydrogen and a reaction time of 4.5 h. The compounds were isolated as white solids in yields ranging from 39% to 72%. The intermediate aminoalditols,1-(1-deoxy-D-glucitol- 1-ylamino)-6-aminohexane (3a) and 1-(1-deoxy-D-galactitol-1-ylamino)-6-aminohexane (3b) were obtained as off-white solids in 80-85% yield. The bolaform amphiphiles containing 1-deoxy-D-glucitol head group(s) showed markedly lower melting points than the compounds with the 1-deoxy-D-mannitol and 1-deoxy-D-galactitol head groups, due to the presence of 1,3-syn interactions within the carbohydrate moiety. The novel bolaform compounds are potential starting materials for the synthesis of a broad range of gemini surfactants with nonidentical, carbohydrate-based head groups. (C) 2004 Elsevier Ltd.
