The stereoselective totalsynthesis of myriocin 1 from D-mannose is described; the carbon framework with three contiguous chiral centers including a tetra-substituted carbon with nitrogen was effectively constructed using Overman rearrangement as the key reaction.

A Ni-catalyzed carboxylation of unactivated primary alkyl bromides and sulfonates with CO2 at atmospheric pressure is described. The method is characterized by its mild conditions and remarkably wide scope without the need for air- or moisture-sensitive reagents, which make it a user-friendly and operationally simple protocol en route to carboxylic acids.
