Vinblastine analogs

Posted by naturalproductman on February 29, 2012

Dale Boger and colleagues have reported in Organic Letters on the functionalization of alkenes using iron. When I first saw vinblastine I thought of Dale Boger because he does so much work on this compound and it looks like I was thinking the right person.

Vancomycin analogs

Posted by naturalproductman on January 6, 2012

Whenever I see vancomycin’s structure I always think of Dale Boger. This time he and co-workers have published in JACS on the synthesis of some vancomycin analogs.

Cribrostatin analogs

Posted by naturalproductman on November 17, 2011

Stephen Martin and colleague have reported in Tetrahedron on their cribrostatin analog synthesis via radical cyclization cascade to access the aromatic ring.  We’ve seen this chemistry before when they reported their synthesis in ACIEE.

A drug for drugs

Posted by naturalproductman on August 24, 2011

You may have seen this in C&E News but for those who missed it:  Danishefsky and co-workers have reported in PNAS on a ginseng analog (poly alkyne) that reduces the side effects of chemotherapy and X-ray treatments.  If you look at the data, then I wouldn’t conclude that the compound drastically improved the side effects of taxol, X-ray and other treatments (3-5% improvement in weight loss, etc), but the idea is interesting and it is a start.
