Stereoselective synthesis of Z and E 3-F-alkyl 2-propenoates and derivatives
摘要:
The stereoselective preparation of 3-F-alkyl 2-propenoates and their derivatives is described. E-isomers are easily obtained by an in situ reduction-olefination from esters of F-acids and phosphonates or by a convenient dehydration of 3-F-alkyl 3-hydroxyesters. Z-isomers an known to be prepared by the hydrogenation of alkynes.
