A cross ene-yne metathesis has been achieved at a nearly 1:1 stoichiometry of the unsaturated reactants. This allowed the use of more complex alkene reactants without sacrificing excess alkene reactant. In the alkene, different allylic oxygen protecting groups were explored. Interestingly, alkenes containing the allylic hydroxyl group proved to be the most reactive.
The invention is directed towards antibacterial compounds. The invention concerns macrolide antibiotics useful as antiinfective agents.
