✦ Synopsis

Alkylation of the anion 4 is only little stereoselective und leads to mixtures of stereoisumeric products SA&9A,B. Proportion qf stereoisomers depends strongly on the base employed. Condensation with acetaldehyde or benzaldehyde leads to four stereoisomeric products llC-F and 12C-F, proportion of which depends also on the bases used.Decomplexation leadr in fhe case of alkylutedproducts to bromides 13, and in the cuse of uldolproduct 11 to brontohydrin 14 and epoxides 1.5 and Id.
