Enantioselective syntheses of cis-4- and trans-3-hydroxypipecolic acids from 2,3-epoxy-5-hexen-1-ol (7) are described. Regioselective C-3 or C-2 ring opening of the epoxide by the appropriate nitrogen nucleophile is the key step in each route. As enantiom
Straightforward entry to the pipecolic acid nucleus. Enantioselective synthesis of baikiain
Ginesta, Xavier,Pericàs, Miquel A,Riera, Antoni
, p. 779 - 782 (2007/10/03)
New enantioselective syntheses of N-protected baikiain and pipecolic acid have been developed. The starting material is 2,3-epoxy-5-hexen-1-ol (4) readily available in high ee by Sharpless epoxidation. The regio- and stereoselective epoxide ring-opening by allylamine afforded a doubly unsaturated amine that was converted into a carbamate (Boc) and submitted to ring-closing metathesis. The resulting cyclic amino diol 6 is a key intermediate that was converted into N-Boc-baikiain and several pipecolic acid derivatives.
