New Directions in C-C Ring Construction: The Overman Synthesis of Guanacastepene N
The opening of epoxides by ketone enolates is notoriously difficult. Marie E. Krafft of Florida State University has found (Chem. Commun. 2006, 2977. DOI: 10.1039/b603510h)a simple solution to this problem.…
Synthesis of (-)-Blepharocalyxin D, (-)-Lasonolide A, and Attenol A
Blepharocalyxin D (3), isolated from the seeds of Alpinia blepharocalyx, shows antiproliferative activity against murine colon 36-L5 carcinoma in cell culture. A key step in the first synthesis of 3,…
Functional Group Protection and Deprotection
Charles M. Garner of Baylor University has described (Tetrahedron Lett. 2006, 47, 7405. DOI: 10.1016/j.tetlet.2006.08.069)the fragmentation of alcohols such as 1 to give the ketone2. The alcohols are prepared by…
