摘要 |
<p>PCT No. PCT/FR91/00406 Sec. 371 Date Nov. 20, 1992 Sec. 102(e) Date Nov. 20, 1992 PCT Filed May 21, 1991 PCT Pub. No. WO91/17977 PCT Pub. Date Nov. 28, 1991.A stereoselective process for preparing phenylisoserine derivatives is disclosed. Benzylamine is reacted with an agent for introducing a phenyl or a t-butoxycarbonyl group. The product undergoes double anionization and then is reacted with acrolein to provide a mixture of alcohol syn and anti diasteroisomers. The syn isomer is isolated by chromatography. Whereupon, the hydroxyl is protected and the product is oxidized to provide the phenylisoserine derivative.</p> |
