GENERATION AND CYCLOADDITIONS OF HYDROXY(AND TRIMETHYLSILOXY)PHENYLETHYNYLKETENE

An unusual rearragement of 5,6-dihydroxy-1,3-dimethoxy-5,6-diphenylethynyl-1,3-cyclohexadiene (1) to 7-hydroxy-1,4-dimethoxy-2-phenylethynylbicyclooctadiene-8-one (2a) was observed when 1 was treated with ZnCl2 in refluxing carbon tetrachloride.The

Synthesis of Alkynyl Quinones and Related Compounds

A general synthetic route to alkynyl-substituted 1,4- and 1,2-benzoquinones is presented.This involves the 1,2-addition of lithium acetylides to a variety of alkoxy quinones followed by hydrolysis of the 3-hydroxy enol ether moiety of the resulting quinols.The use of these quinols and alkynyl quinones in the synthesis of various aromatic phenols and potential bioreductive alkylating agents is also presented.
