Expanding Diversity without Protecting Groups: (+)-Sclareolide to Indolosesquiterpene Alkaloid Mycoleptodiscin A and Analogues.

Organic letters

Nagaraju K, Chegondi R, Chandrasekhar S.
PMID: 27181938
Org Lett. 2016 Jun 03;18(11):2684-7. doi: 10.1021/acs.orglett.6b01145. Epub 2016 May 16.

Short and scalable synthesis of the complex pentacyclic indolosesquiterpene natural product mycoleptodiscin A has been achieved from commercially available diterpenoid (+)-sclareolide in 19% overall yield. This approach allows one to prepare various analogues of mycoleptodiscin using McMurry cyclization as...
