The invention relates to a paclitaxel analogue with modified C-13 and C-14 positions and a preparing method of the paclitaxel analogue. The structural formula of the analogue is shown in the description. Different side chains are introduced into the C-13 position and the C-14 position of taxanes of 1-dehydroxybaccatin VI, the annular framework and necessary functional groups of paclitaxel are reserved, paclitaxel compounds are enriched, the obtained compounds have the natural anti-cancer biological activity of natural paclitaxel, certain application prospects on the aspect of reducing the toxic and side effects of natural paclitaxel are achieved, and meanwhile it is highly beneficial for studying the activity structure-function relationship of the compounds. The compounds a, b, c, d and taxol have a suppressing effect on the in-vitro proliferation of the A 549 lung cancer cells, A 2780 ovarian carcinoma cells and HL-60 promyelocytic leukemia cells of the human body.

A variety of substituted 1-aryl-2-propenylamines of high enantiomeric purity were prepared via lipase-catalysed resolution of the corresponding racemates. (R)-1-Phenyl-2-propenylamine was further synthesised into (2R,3S)-3-benzoylamino-2-hydroxy-3-phenylpropanoic acid methyl ester, the side chain of Taxol.

Dihydrodihydroxycinnamic acids and their esters react with acetonitrile or benzonitrile in the presence of sulfuric acid to afford the corresponding syn-β-amino-α-hydroxypropionic acid derivatives. High yields and diastereoselectivity of this transformation allows preparation of various phenylisoserine derivatives on a practical scale.
