✦ Synopsis

main product 19, ca. 20% of another stereoisomer. This results from a partial racemization of the ketone 5 occurring during its distillation or during the formation of 18. This follows from the condensation of racemic 5 with the aldehyde 15 affording with a 4: 1 selectivity the above mentioned by-product, which must therefore be 12-epi-19.

The asymmetric alkylation with diethylzinc of five heterocyclic aldehydes and benzaldehyde (for comparison) has been studied in the presence of two optically active amino alcohols: (S)-2-amino-1-butanol (AB) and (1S,2R)-N,Ndibutylnorephedrine (DBNE). A number of chiral (hetero)aromatic secondary alc
