Efficient synthesis and X-ray structures of new α-quinolin-3-yl-α-aminonitriles and derivatives
摘要:
This study describes the synthesis of novel alpha-aminonitrile derivatives possessing a quinoline subunit via a Strecker reaction. Chiral alpha-methylbenzylamines were used to carry out the diastereoselective version of this sequence. Conversion of an enantiopure 2-chloroquinolin-3-yl derivative into the corresponding alpha-aminoester resulted in the concomitant formation of a 2(1H)-quinolinone moiety and a partial racemization. Single crystal X-ray structures are reported for three compounds. (C) 2012 Elsevier Ltd. All rights reserved.
已经开发了一种简单,方便的顺序一锅法合成1,2,3,4-四氢苯并[ b ] [1,6]萘啶。在硼氢化钠存在下,用各种胺对2-氯-3-甲酰基喹啉进行还原性胺化反应可提供高产率的相应仲胺。此外,对仲胺进行了涉及N-烯丙基化和分子内Heck型6-exo-trig环化的顺序一锅反应,得到了所需的1,2,3,4-四氢苯并[ b ] [1,6]对-萘啶衍生物的产率高至高。
