摘要

New dienoxysilanes of the general formula: BR/ (CF DRAWING IN BOPI) BR/ BR/ and new alpha-halogenated alpha-ethylenic aldehydes to which they give access, of the general formula: BR/ (CF DRAWING IN BOPI) BR/ BR/ These new compounds are important synthetic intermediates opening a new way of access to macrolides such as pyrenophorin, norpyrenophorin or vermiculin.
