  Allylsilanes in the preparation of 5′-C-hydroxy or bromo alkylthymidines

  摘要：

  The reaction of 5'-C-thymidine aldehyde with allytrimethylsilane promoted by BF3:Et2O lead stereoselectively to 5'-C(S)-allylthymidine which is converted to 5'-C(S) C(S)-hydroxyhexylthymidine. 5'-C-(R or S) hydroxypentylthymidine can be obtained by using omega-tertButyldimethylsilyloxyallyltrimethylsilane in the Sakurai reaction. In the same conditions, omega-Bromoallyltrimethylsilane adds to the aldehyde with a complete transposition of the siliranium intermediate and allows the preparation of the 5'-C(S)-bromopentene derivative, (C) 1999 Elsevier Science Ltd.
