  Synthesis of asymmetrized 2-benzyl-1,3-diaminopropane by a chemoenzymatic route: a tool for combinatorially developing peptidomimetics

  摘要：

  Both enantiomers of monoacetamide 5, together with 'dipeptides' 30a,b and monocarbamates 24, (R)-43 and (S)-43, all derived from 2-benzyl-1,3-diaminopropane 4, were synthesized by a chemoenzymatic route starting from the known monoacetate 12. The behaviour of 4 and of the bis(acylated) derivatives 8-11 with respect to hydrolytic enzymes is also presented, together with an extensive study on the configurational stability of monoacylated derivatives of 4.

  A wide range of prochiral 1,3-diamines were first efficiently synthesized and subsequently desymmetrized by using lipase from Pseudomonas cepacia as catalyst and diallyl carbonate as alkoxycarbonylating agent. In all cases, the amino carbamates of R-configuration were recovered. Final selective cleavage of the N-allyloxycarbonyl moiety was carried out under mild reaction conditions, which demonstrates

  首先有效地合成了多种前手性的1,3-二胺，然后使用洋葱假单胞菌的脂肪酶作为催化剂，碳酸二烯丙酯作为烷氧基羰基化剂进行了脱对称。在所有情况下，都回收了R-构型的氨基氨基甲酸酯。N-烯丙氧羰基部分的最终选择性裂解是在温和的反应条件下进行的，这表明该化学酶促途径具有很高的通用性和潜力，可作为相关旋光性氮化衍生物合成中的中间体来源。
