An efficient stereoselective synthesis of (2S,3S)-3-hydroxypipecolic acid using chlorosulfonyl isocyanate

Research output: Contribution to journalArticlepeer-review

Abstract

An efficient stereoselective syntheses of (2S,3S)-3-hydroxypipecolic acid and (2R,3S)-2-hydroxymethylpiperidin-3-ol were achieved from p-anisaldehyde via the regioselective and diastereoselective introduction of an N-protected amine group using chlorosulfonyl isocyanate, ring-closing methathesis, and oxidation of p-methoxyphenyl group as the key steps.
