Patent number: 6660741
Abstract: The present invention provides methods for the asymmetric synthesis of (S,S,R)-(−)-actinonin and its analogs and the compounds thereby synthesized having a structural formula:
where R1 is an optionally substituted or halogenated alkyl, aryl, heteroalkyl or heteroaryl amine, said R1 further comprising a cyclic or bicyclic structure; R2 is methyl, CH2CH3, (CH2)2CH3, C(CH3)3, phenyl, 3,4-dichiorophenyl, biphenyl, benzyl, 4-hydroxybenzyl, piperidine, N-Boc-4-piperidine, CH2-(N-Boc-4-piperidine), 4-tetrahydropyran, CH2-4-tetrahydropyran, 3-methyl indolyl, 2-naphthyl, 3-pyridyl, 4-pyridyl, 3-thienyl; R3 is R2 or C3-8alkyl, R4 is C1-3alkyl; and R5 is NH2, OH, NHOH, NHOCH3, N(CH3)OH, N(CH3)OCH3, NHCH2CH3, NH(CH2CH3), NHCH2(2,4-(OCH3)2Ph, NHCH2(4-NO2)Ph, NHN(CH3)2, proline, or 2-hydroxymethyl pyrrolidine.
