Clavalanine (Ro 22-5417), a New Clavam Antibiotic from Streptomyces clavuligerus. 4. A Stereorational Synthesis

Clavalanine (Ro 22-5417), a new β-lactam antibiotic, 3-hept-3-yl>-L-alanine (1), was synthesized by a route in which D-xylose (4) supplied the stereochemical requirements.From 4 was elaborated a (2S,4S)-2-amino-4,5-
