Synthesis and absolute configuration of (+)-2,3,3-trimethyl-2-hydroxybutanoic acid
摘要:
The absolute configuration of (+)-2,3,3-trimethyl-2-hydroxybutanoic acid, a key intermediate in the synthesis of the HIV-protease inhibitor 1a (isomer A), has been confirmed as (R) on the basis of X-ray analysis.

The ene reaction of singlet oxygen with alkenes in the presence of titanium alkoxides was employed to prepare epoxyalcohols in high diastereoselectivity; enantioselectivity could be achieved by use of diethyl tartrate as chiral auxiliary.
