METHOD FOR PRODUCING 4- TO 6-MER OF CATECHIN AND EPICATECHIN

PROBLEM TO BE SOLVED: To provide a method for producing a 4- to 6-mer of catechin or epicatechin optical selectively and efficiently. SOLUTION: The 4- to 6-mer of catechin can be produced efficiently by using a 3- to 5-mer of catechin as a nucleophile, and a catechin monomer as an electrophile, and by reacting them in the presence of silver triflate (Ag(CF3SO3)). Furthermore, the 4- to 6-mer of epicatechin can be produced efficiently by using a 2-mer of epicatechin as a nucleophile, and a 2- to 4-mer of epicatechin monomer as an electrophile, and reacting them in the presence of zinc triflate (Zn(CF3SO3)2).

Synthesis of Condensed Tannins. Part 13. The First 2,3-trans-3,4-cis-Procyanidins: Sequence of Units in a 'Trimer' of Mixed Stereochemistry

The condensation of (+)-leucocyanidin with (-)-epicatechin initiates a succession of substitutions leading mainly to the introduction of -2,3-trans-3,4-procyanidin units, but also to the incorporation of 'terminal' moieties which possess the hitherto unique 3,4-cis-procyanidin configuration.The bonding patterns in the products, and also the sequence of units in one of the 'trimers' of mixed stereochemistry, are resolved by (1)H n.m.r. spectroscopy through selective use of solvents at elevated temperatures.
