STEREOSELECTIVE CONDENSATIONS OF α'-LITHIO PYRROLIDINE AMIDINES
Sanner, Mark A.
, p. 1909 - 1912 (2007/10/02)
The condensation of α'-lithio pyrrolidine amidine 5 with aromatic aldehydes gives hydroxymethyl pyrrolidines 6 with high threo-erythro selectivity (ca. 95:5).In contrast, the analogous reaction with lithiopiperidine amidine 9 is stereorandom.
