Chiral acyclonucleosides were synthesized by an organocatalytic asymmetric aza‐Michael addition reaction from achiral purine bases and α,β‐unsaturated aldehydes in 82–89 % yield and up to 99 % ee. The isolated chiral acyclonucleosides are readily converted to acyclonucleotides.
通过非手性嘌呤碱和α,β-不饱和醛的有机催化不对称aza-Michael加成反应合成了手性无环核苷,产率为82-89%,ee高达99%。分离的手性无环核苷易于转化为无环核苷酸。
