The relative contributions of nucleophilicity and steric hindrance in determining the course of the reacition during the formation of 'angular' triflavonoids are examined by biomimetic-type condensations involving model compounds.Key Word Index - (4,6)-(-)-fisetinidol-8-(4-hydroxybenzyl)-(+)-catechins; 4-(3-ethyl-2,4,6-trihydroxyphenyl)-3,3',4',7-tetrahydroxyflavans; (4,3:4,5)-bi--ethyl phloroglucinols; condensed tannins; nucleophilicity; steric hindrance.
