The tetrachlorinated natural product (-)-dysithiazolamide was synthesized from L-glutamic acid in a convergent way, confirming the previously proposed (2S,4S,6S,8S) absolute stereochemistry.

One for all: A group of polychlorinated marine peptides known as sintokamides show intriguing activity against hormone‐refractory prostate cancer cells. Three members of the group have now been synthesized by a general strategy enabled by a ruthenium‐catalyzed radical chloroalkylation of titanium enolates (see scheme).
