摘要:
AbstractA convenient method for the generation of (+)‐sedamine and (+)‐allosedamine in high optical purity has been elaborated. The key steps are the highly stereoselective 1,2‐nucleophilic addition to SAMP hydrazones allowing the installation of the stereogenic center at C2 and ring closing metathesis.
