Starting from R,R-(+)-tartaric acid, the synthesis of (2S,3R,4R6E)-3-hydroxy -4-methyl-2-methylamino-6-octenoic acid in 24 steps is reported. This novel amino acid is found in the cyclic undecapeptide cyclosporin A, isolatedfrom the fungal strain Tolypocladium inflatumGAMS. Its stereospecific synthesis allowed, for the first time, the isolation and characterization of the new amino acid previously
从R,R -(+)-酒石酸开始,报道了24步合成(2 S,3 R,4 R 6 E)-3-羟基-4-甲基-2-甲基-2-甲基氨基-6-辛烯酸。该新氨基酸存在于从真菌菌株Tolypocladium inflatum GAMS分离的环状十一肽环孢菌素A中。它的立体定向合成首次允许分离和表征先前报道为“ C-9-氨基酸”的新氨基酸[1]。
