Racemic, stereoisomeric decal-1-ones and several related bicyclic and tricyclic ketones have been reduced microbiologically with high stereospecificity by Curvularia falcata (TEHON) BOEDIJN. The constitution, and the relative and absolute configuration, of the products have been determined.

The reaction of 1β-acetoxy-8aβ-methyl-Δ4α(5)-6-octalone with an excess of diborane followed by treatment of the resulting organoboranes with acetic anhydride affords in poor yield a mixture of two isomeric octalins which are determined to be trans- and cis-1β-acetoxy-8aβ-methyl-Δ5-octalin on the basis of spectral data and conversion of one of them into the known trans-8a-methyl-1-decalone. The spectral

The substituent effects of the hydroxyl group on the 13C shieldings of the trans-decalols and the 10-methyl-trans-decalols have been determined. The shifts for the carbons three and four bonds from...
