A New Access Route to Functionalized Cispentacins from Norbornene beta-Amino Acids

[摘要]：An efficient and simple new stereocontrolled access route to novel disubstituted cispentacin derivatives with multiple stereogenic centers from norbornene -lactam has been developed. The synthesis involves olefinic bond functionalization by dihydroxylation followed by oxidative ring cleavage and transformation of the dialdehyde intermediate through a Wittig reaction. Norbornenvazas -laktambol kiindulva sztereokontrollalt atalakitasokkal negy sztereogen centrumot tartalmazo diszubsztitualt ciszpentacin szarmazekokat allitottunk el. A szintezisut kulcslepesei a gyr szen-szen ketts kotesenek dihidroxilalasa, majd oxidativ gyrnyitast kovet Wittig reakcioval torten funkcionalizalasai voltak.
