The total synthesis of racemic tricyclovetivene ( l a ) and isomers ( l b and 26) is described. The crucial reaction of the synthesis is a cyclization (iii) developed in this laboratory.La synthtse totale du tricyclovetiv6ne ( l a ) racemique et de ses isomtres ( l b et 26) est dkcrite. L'etape cruciale de la synthtse est une cyclisation (iii) mise au point dans ce laboratoire.
(E)-(2S)-2-Amino-4-methylthio-3-butenoic acid (1; "dehydro-L-methionine") was prepared through reaction stages 2-7 using p-acetamido-p, P-di(ethoxycarbony1)propionaldehyde as starting material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
