title: Applications of Crotonyldiisopinocampheylboranes in Synthesis: Total Synthesis of Restrictinol.
abstract: The total synthesis of restrictinol, the hydrolysis product of the antifungal natural product restricticin, starting from commercially available methyl (S)-(+)-3-hydroxy-2-methylpropionate is described. Key stages in the strategy involved (i) the use of Brown's allylboration chemistry to construct an acyclic intermediate bearing three of the four stereogenic centers of the natural product, (ii) formation of a C-glycosidic vinyl iodide, and (iii) introduction of the triene side chain via a Suzuki coupling reaction.
