摘要
The enaminone (4), prepared from (2S)-pyroglutamic acid, has been reacted with Grignard reagents to afford a variety of (E)-alkylidene derivatives (8). Three of these have been converted to the 4-alkylideneglutamic acids, (1), (2) and (3), which are identical to known natural products, (2) and (3) being the E-isomers.
