Galbulimima Alkaloids (-)-GB 13 and (+)-GB 16

Ma, Zi, Yu. ACIEE, 2010, EarlyView. DOI: 10.1002/anie.201002299.
Why make one natural product when you can make two just as easily?  Or three in this case, but the headline syntheses are the Galbulimima Alkaloids GB-13 and GB-16 – notable members of a family that is getting some serious attention in pharma – one analogue is currently in phase III trials.  With all that potential, it’s not surprising that these beasties have seen quite a bit of synthetic attention; indeed, GB-13 was one of the first syntheses I …

Aplykurodinone 1

This month’s Chemistry World column is Aplykurodinone 1, a rather neat Danishefsky synthesis.
