67. Diversity-Oriented Approach to Cyclophanes via Fischer Indolization and Ring-Closing Metathesis: Substrate-Controlled Stereochemical Outcome in RCM.

Author

Kotha, Sambasivarao, Chinnam, Ajay Kumar, and Shirbhate, Mukesh E.

Subjects
*CYCLOPHANES, *METATHESIS reactions, *STEREOCHEMISTRY
Abstract

It is found that the configuration of the double bond formed during the RCM depends on the order of the synthetic route. The Fischer indolization followed by RCM lead to the cis-isomer, whereas the RCM followed by Fischer indolization lead to the trans-isomer. [ABSTRACT FROM AUTHOR]
