Synthesis of enantiomerically pure carbocyclic α-l-isomeric homonucleosides
摘要:
Synthesis of hitherto unknown carbocyclic alpha-L-isomeric homonucleosides (8a-b, 9a-b) is described. The key intermediate 6 was synthesized from the known compound I as a chiral starting material. Construction of the heterocyclic moiety around the amino group of 6 afforded carbocyclic alpha-L-isomeric 2',3'-dideoxyhomanucleosides 8a-b and their 2',3'-didehydro-2',3'-dideoxy derivatives 9a-b.
