is described using two consecutive organometallic transformations: a novel zinc-mediated domino reaction to give functionalized dienes followed by ring-closing olefin metathesis. In the first reaction, methyl ω-deoxy-ω-iodo glycosides undergo reductive elimination with zinc to produce a terminal double bond. This also liberates the aldehyde which is immediately alkylated in situ by various organozinc

A short and economical synthesis of 3-deoxy-D-arabino-2-heptulosonic acid (4) and 3-deoxy-D-arabino-2-heptulose (kamusol, 8) has been developed. In the key step of the reaction sequence, the indium mediated allylation of D-erythrose in an aqueous solvent system was utilized generating a seven carbon backbone which was further transformed into the title compounds.
