(4R,5S)-4-Methyl-5-phenyloxazolidin-2-one was used as a chiral template to construct the 8S and 9S chiral centres of (2S,3S,8S,9S)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldeca-4,6-dienoic acid (ADDA), the 2S and 3S centres were derived from D-aspartic acid.
                                    以(4 R,5 S)-4-甲基-
5-苯基恶唑烷丁-2-酮为手性模板,构建(2 S,3 S,8 S,9 S)-的8 S和9 S手性中心。3-
氨基-9-甲氧基-2,6,8-三甲基-10-苯基癸-4,6-二烯酸(A
DDA)的2 S和3 S中心衍生自
D-天门冬氨酸。
