Convenient syntheses of (3S,5S)-carbapenam-3-carboxylates and their biosynthetic relevance
摘要:
Starting from readily available glutamate derivatives, facile stereoselective syntheses of (3S,5S)-carbapenam-3-carboxylates have been developed. Their significance in confirming the absolute configuration of the natural material is discussed. (C) 2003 Published by Elsevier Science Ltd.
