D. Crich et al., THE CHEMISTRY OF CYCLIC TAUTOMERS OF TRYPTOPHAN - HIGHLY DIASTEREOSELECTIVE ALDOL CONDENSATIONS, Heterocycles, 38(4), 1994, pp. 719-724
Highly diastereoselective aldol reactions of a cyclic tryptophan tauto
mer (1) are reported, together with stereochemical assignments of the
products and a possible rationale for the selectivity.
