Cyclic hydroboration of geraniol derivatives: a synthesis of the left-hand portion of X-14547A
The stereochemical consequences of the cyclic hydroboration-oxidation of geraniol derivatives have been examined; moderately high selectivity (85-88 percent) for the formation of one major diastereomer has been observed, presumably as a consequence of remote asymmetric induction in the cyclic hydroboration of these 1,5-dienes.An approach to the synthesis of the left-hand portion of the ionophore antibiotic X-14547A is described.
