Stereoselective Synthesis of Deuterium-Labeled (2S)-Cyclohexenyl Alanines, Biosynthetic Intermediates of Cinnabaramide
摘要:
Dideuterated beta-cyclohexenylalanines, proposed biosynthetic intermediates of the cinnabaramides, can be obtained from chiral alkynols via a sequence of Irland-Claisen rearrangement, ring closing metathesis, and radical decarboxylation. Feeding experiments indicate that both (2S)-beta-cyclohexenylalanines can be incorporated into cinnabaramide, while the configuration at the cyclohexenyl ring does not restrict biosynthetic processing.
