## Abstract The conformational free energies for some 2โ€substituted butanes where X = F, Cl, CN, and CCH were calculated using G3โ€B3, CBSโ€QB3, and CCSD(T)/6โ€311++G(2d,p) as well as other theoretical levels.

Lipase-mediated acetylations of trans-and cis-2-substituted cyclohexanols gave the corresponding (1R)-cyclohexyl acetates and (1S)-cyclohexanols in high yields and ee, but c-4-tert-butyl-c-2-ethenyl-r-1-cyclohexanol was unreactive owing to the steric interaction between the axial OH group and the ax
