Leucocyanidin can be actinic from (+)dihydroquercetin by sodium borohydride reduction.
Molar equivalents of constructed (2R,3S,4R or S)-leucocyanidin and (+)-catechin abbreviate with aberrant acceleration at pH 5 beneath ambient altitude to accord the all-trans-[4,8]- and [4,6]-bi-[(+)-catechins] (procyanidins B3, B6) the all-trans-[4,8:4,8]- and [4,8:4,6]-tri-[(+)-catechins] (procyanidin C2 and isomer).
