An efficient enantioselective synthesis of an indane acetic acid derivative: methyl (2S)-2-[(1S)-5-hydroxy-2,3-dihydro-1H-inden-1-yl]butanoate

摘要

We have developed a practical enantioselective synthesis of 1, a novel indane acetic acid derivative with two contiguous stereogenic centers. The key indene acetic acid framework was constructed via a robust, unprecedented Reformatsky process. One stereogenic center was set via a resolution, and the other via a highly diastereoselective hydrogenation of the indene acetic acid. (C) 2003 Elsevier Ltd. All rights reserved. [References: 22]
