Enantioselective α-deprotonation-rearrangement of achiral substituted cyclooctene oxides 7, 27 and 28 and N-Boc hexahydroazonine oxide 45 using organolithiums in the presence of (-)-sparteine 3 or (-)-α-isosparteine 4 gives the functionalised bicyclo[3.3.0]octan-2-ols 9, 29, and 32 and indolizinol 47 in 50-72% yields and 83-89% ees.
