Alkylations and Allylations. The asymmetric alkylation of chiral enamines derived from (S)-proline esters has been disclosed. The a-alkylation of cyclohexanone proceeds with an optical purity of 59%. (5)-Proline catalyzes the alkylation of xanthopurpurin (34) by 2-hydroxytetrahydropyran yielding... [Pg.482]

After the first isolation of alizarin a lot of other anthraquinones were isolated from Rubia tinctorum for example purpurin, munjistin, rubiadin, pseudopurpurin, nordamnacanthal, lucidin, xanthopurpurin and anthra-gallol. [Pg.657]

Madder is characterised by the presence of a series of key anthraquinone components, the most important of which are alizarin, purpurin and pseudopurpurin, molindone, xanthop-urpurin, rubiadin (qq.v.), although a large group of other anthraquinones is also present. Schweppe and Winter list the following additional components found in the various madder species munjistin, ibericin, lucidin, 2-hydroxyan-thraquinone, xanthopurpurin-3-methyl ether, alizarin-1-methyl... [Pg.244]
