Abstract: front page image
(EN)Optically active hydroxymethylpiperazines represented by general formula (1), useful as catalysts for asymmetric synthesis and so on; and intermediates for the preparation of the same, wherein R1 is hydrogen, alkyl, cycloalkyl, optionally substituted aralkyl or the like; R2 is hydrogen or a protecting silyl group; X is carbonyl or sulfonyl; and Y is optionally substituted alkyl, alkenyl, cycloalkyl, aryl or the like.
(FR)L'invention porte sur des hydroxyméthylpipérazine de formule générale (1) utilisables comme catalyseurs de système asymétrique etc., et sur leurs intermédiaires de préparation. Dans la formule (1) R1 est H, alkyle, cycloalkyle, aralkyle facultativement substitué, ou analogue; R2 est H ou un groupe protecteur silyle; X est carbonyle ou sulfonyle; et Y est alkyle, alcényle, cycloalkyle, aryle ou analogue, facultativement substitués.
