74518-57-3 Usage

Occurrence

A glucosidic sulphur-containing alkaloid, xylostosidine occurs in the water-soluble fraction of the extract of Lonicera xylosteum. It forms colourless needles when crystallized from MeOH and is laevorotatory with a specific rotation of [α]D -289.37° (c 0.56, MeOH). The ultraviolet spectrum in MeOH consists of a single absorption maximum at 238 nm. Acetylation furnishes the tetraacetate which is laevorotatory with a specific rotation of [α]D20D -85.35° (c 0.35, CHCl3).

Check Digit Verification of cas no

The CAS Registry Mumber 74518-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,1 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74518-57:
(7*7)+(6*4)+(5*5)+(4*1)+(3*8)+(2*5)+(1*7)=143
143 % 10 = 3
So 74518-57-3 is a valid CAS Registry Number.

Iridoids, 24. - Biomimetic Synthesis of the Monoterpene Alkaloids Xylostosidine and Loxylostosidine A and of Similar Unnatural Compounds by Transformations of the Monoterpene Glycoside Secologanin

Tietze, Lutz F.,Baertels, Christoph,Fennen, Jens

, p. 1241 - 1246 (2007/10/02)

Condensation of secologanin (1) with cysteamine (5a) affords diastereoselectively 71percent of xylostosidine (2), which was transformed into loxylostosidine A (3) by treatement with m-chloroperbenzoic acid in 70percent yield.Similarly, reaction of the functionalized amines 5b, c, 6a-c, and 7 with 1 yields the unnatural monoterpene alkaloids 8-13.The condensation of 1 with 5a was followed by time-resolved NMR spectroscopy to reveal the stereoselectivity in this transformation.
