—— | (-)-(2R,1'S)-8-benzyloxy-2-(1'-hydroxyethyl)-5-methoxy-1,2,3,4-tetrahydronaphthalen-2-ol | 90744-27-7 | C20H24O4 | 328.408 |
The title dienones have been prepared from (-)-(2R,1′S)-8-benzyloxy-2-(1′-hydroxyethyl)-5-methoxy-1,2,3,4-tetrahydronaphthalen-2-ol, by a series of reactions in which the selective cleavage of an aryl methyl ether in the presence of an aryl ethyl ether plays a key role. This 10- step sequence proceeds in an overall yield of 55%, and chiral integrity is preserved throughout.
