Abstract
6(R)-[2-(8'-Etherified-hydroxy-2',6'-dimethylpolyhydronaphthyl-1')-ethyl]-4 (R)-hydroxy-3,4,5,6-tetrahydro-2H-pyran-2-ones are prepared from the corresponding 8'-acyloxy compounds, some of which are naturally occurring, by protection of the 4(R)-hydroxyl and the 2-keto group, followed by reductive removal of the 8'-acyloxy group, etherification of the resulting 8'-hydroxyl and removal of the protecting groups. The products inhibit the biosynthesis of cholesterol.
