Efficient Synthesis of Carbocyclic Nucleoside, (±)-Homocarbovir Via π-Allylpalladium Complex Formation from the Allyl N,N-Ditosylimide Substrate
摘要:
The synthesis of a carbovir analogue, (+/-)-homocasbovir (3) was achieved from norbornadiene (4) in seven steps and 27% overall yield. This route involves a Meinwald-type rearrangement, an acid-hydrolysis of N-tosyl bicyclic enamine 5, and a Pd(0)-catalyzed coupling reaction.
