  Stereoselective divergent synthesis of 1,2-aminoalcohol-containing heterocycles from a common chiral nonracemic building block

  摘要：

  gamma-N,N-Dibenzylamino-beta-hydroxysulfoxide 1 proved to be an excellent chiral building block for the synthesis of a range of 1,2-amino alcohol-containing heterocycles. Thus, I was converted into 4,5-disubstuted oxazolidin-2-one 4 and aminoepoxides 2 and 3. Aminoepoxide 2 proved to be an excellent precursor to access oxazolidin-2-one 5 and azetidin-3-ol 6. Finally, 2 was used as a key intermediate that allowed the development of a divergent strategy to access cis-2-methyl-6-substituted piperidin-3-ol alkaloids. (+)-Deoxocassine 7 and a C-6 ethyl analogue 8 were prepared to illustrate this approach and to demonstrate that this strategy should be adaptable to the production of other members of this alkaloid family.

  Enantiomerically pure oxazolidinones are easily prepared from N,N-dibenzylamino epoxides through a one-pot procedure involving monodeprotection of the amino group and treatment with NaHCO3.

  对映体纯度极高的噁唑烷酮类化合物很容易从 N,N-二苄基氨基环氧化物中制备出来，制备过程只需对氨基进行单保护并用 NaHCO3 进行处理。
