  Iodomethylation of Chiral α-Amino Aldehydes by Means of Samarium/Diiodomethane. Application to the Synthesis of Various Enantiomerically Pure Compounds

  摘要：

  Chiral iodohydrins 2 have been obtained from alpha-amino aldehydes 1 and Sm/CH2I2. Treatment of compound 2 with acetic anhydride, NaH, or AgBF4 affords, with high diastereoselectivity, O-protected 3-(dibenzylamino)-1-iodoalkan-2-ol 3, amino epoxides 4, or azetidinium salts 5, respectively. The synthesis of enantiomerically pure allylamines 6 is also described by metallation of 3 with zinc. The reaction of a-amino aldehydes 1 with Sm/CH2I2 and further treatment with organocuprates affords chiral amino alcohols 7 in a one-pot process.

  Enantiopure aminoiodohydrins obtained from a-aminoaldehydes and Sm/CH2I2 have been transformed into regioisomeric aminoiodohydrins, aminoepoxides, azetidines or 1,3-oxazolidines. The key step in these transformations is a nucleophilic opening-closing process. (C) 2000 Elsevier Science Ltd. All rights reserved.
