Fd. Bellamy et al., ENANTIOSELECTIVE SYNTHESIS OF 4 ISOMERIC BUILDING-BLOCKS USEFUL IN THE SYNTHESIS OF 2-NOR-LEUKOTRIENE ANALOGS, Tetrahedron : asymmetry, 3(3), 1992, pp. 355-358
We report, in this letter, the enantioselective synthesis of four isom
eric functionalized epoxides (3a, 3b, 3c and 3d) which are useful buil
ding blocks for the synthesis of 2-nor-leukotriene analogues. All four
epoxides are formally derived from a single non chiral starting mater
ial, the 2-butyne-1,4-diol 7.
