In this paper, the use of L - (+) - dimethyl tartrate as a starting material and the development of a simple and efficient method, on the one hand can also improve the previous reproducibility and side effects of the problem can be prepared by the diversity of optical pure 2 - hydroxy fatty acids. And we also use this method to complete the 2-hydroxy octadecanoic acid derivative TA-11 asymmetric synthesis. In this case, the four constructs were synthesized by chemically selective glycosylation and [1 + 1 + 2], and NGLF-1 and NGLF-1 (9- OMe).
