Herein we utilized a new methylene carbenoid as an extremely simple and highly practical reagent for the preparation of vinyl ether with good to excellent yield. This method efficiently effects methoxymethylenation or vinyl ether formation of enolizable, nonenolizable, and sterically hindered ketones. The complexation of Ti–Mg–CHOMe was facilitated, presumably, by THF dramatically increasing the feasibility; and scope of this protocol is to produce vinyl ethers which can be used as convenient building blocks for the preparation of biologically useful molecules.

The palladium-catalyzed oxidation of alkyl enol ethers to enals, which employs low loadings of a palladium catalyst, is described. The mild oxidation conditions tolerate a diverse array of functional groups, while allowing the formation of di-, tri-, and tetrasubtituted olefins. The application of this methodology to intramolecular reactions of alkyl enol ethers containing pendant alcohols provides furan and 2,5-dihydrofuran products.

Compounds of formula (I) and their salts and esters: STR1 wherein X is hydrogen or a group NHR1, wherein R1 is hydrogen or an amino protecting group, and R is optionally substituted C5-8 cycloalkyl or cycloalkenyl, are useful in the treatment of bacterial infections.
