  (S)-4-(1H-indol-3-ylmethyl)-5,5-dipropyl-3-(1-oxo-but-2-enyl)-oxazolidin-2-one 在 bis(isopropyloxy)chloroborane 作用下， 以 二氯甲烷 为溶剂， 反应 72.0h， 生成 (S)-3-((S)-3-Chloro-butyryl)-4-(1H-indol-3-ylmethyl)-5,5-dipropyl-oxazolidin-2-one 、 (S)-3-((R)-3-Chloro-butyryl)-4-(1H-indol-3-ylmethyl)-5,5-dipropyl-oxazolidin-2-one

  Conjugate addition of chloride to α,β-unsaturated chiral imides promoted by BCl3-derivatives. Part II

  摘要：

  The diastereoselective hydrochlorination of alpha,beta-unsaturated chiral imides by reaction with BCl(2)OR or BCl(OR)(2) type reagents is described. Complete diastereoselectivity is achieved through the use of new oxazolidin-2-ones ad hoc prepared for this purpose from (S)-tryptophan. An hypothesis on the donor-acceptor interactions, between the substrate and the Lewis acids, that drive the attack of the chloride preferentially to one face of the alkenoyl chain is reported.

  The synthesis of chiral aminoalcohols 4 derived from (S)-tryptophan is described, by reaction of the protected amino acid 3 with various Grignard reagents. The aminoalcohols were transformed into the corresponding oxazolidin-2-ones 2 and acylated with 2-butenoyl chloride and 2-hexenoyl chloride, affording the imides 5a-e. The conformational analysis of both the oxazolidin-2-ones 2 and the Michael acceptors
