The enantioselective total synthesis of the telomerase inhibitor UCS1025A has been accomplished. The key transformation involves a remarkable boron Reformatsky coupling of iodolactone 13 and aldehyde 17.

activity associated with a subfamily of the tetramic acid class of natural products. Despite the fact that members of this subfamily act as protein–protein interaction inhibitors that are of relevance to proteasome assembly, no synthetic work has been reported. This may be due to the fact that this subfamily contains an unnatural 4,4‐disubstitued glutamic acid, the synthesis of which provides a key challenge
