154905-69-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 154905-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,9,0 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 154905-69:
(8*1)+(7*5)+(6*4)+(5*9)+(4*0)+(3*5)+(2*6)+(1*9)=148
148 % 10 = 8
So 154905-69-8 is a valid CAS Registry Number.

New sesquiterpenoids from Lycianthes marlipoensis

Guo, Fujiang,Li, Yuanchao

, p. 2364 - 2369 (2005)

Two new sesquiterpenoids and one derivative, lycifuranone A (= (4R)-4,5-dihydro-4-(3-hydroxy-2,6-dimethylbenzyl)-5,5-dimethylfuran-2(3H)-one; 1), lycifuranone B (= 4,5-dihydroxy-3-methyl-2-1{[(3R)-tetra-hydro-2,2-dimethyl- 5-oxofuran-3-yl]methyl} benzaldehyde; 2), and lycifuranone C (= (4R)-4-(3,4-dihydroxy-6-{(2S,4R,6S)-4-[2-(4-hydroxy-3-methoxyphenyl)ethyl] -6-pentyl[1,3]dioxan-2-yl}-2-methylbenzyl)-4,5-dihydro-5,5-dimethylfuran-2(3H) -one; 3), respectively, have been isolated from the roots of Lycianthes marlipoensis, and their structures were established by spectroscopic methods.

A chiral pool and cross metathesis based synthesis of gingerdiols

Wan, Zhi-Li,Zhang, Guo-Liang,Chen, Hui-Jun,Wu, Yikang,Li, Yan

, p. 2128 - 2139 (2014/04/17)

Both (3R,5S)- and (3R,5R)-gingerdiols were synthesized. Their 1,3-diol motifs were derived from enantiopure epoxy chiral building blocks that were readily accessible from D-gluconolactone. The effect of deuterating the OH groups of the natural isomer on its optical rotation was also examined. In the course of the syntheses of the targets, an unexplored cross-metathesis (CM) reaction of unprotected 5-substituted pent-1-ene-3,5-diols was investigated, in which the CM product readily underwent an allylic epimerization and oxidation, as the starting diols rearranged into ketones with unprecedented ease. These problems were eventually resolved by performing the CM reaction in toluene in the presence of phenol. The cause of these unexpected, yet very interesting phenomena, was determined to be the presence of the unprotected OH group at C-5 of the 5-substituted pent-1-ene-3,5-diol. A mechanistic rationale is also presented. Copyright

A new method for the demetallation of tricarbonyliron diene complexes by total hydrogenation with Raney nickel. Application to a very short synthesis of (+)-[6]-gingerdiol

Franck-Neumann, Michel,Geoffroy, Philippe,Bissinger, Paul,Adelaide, Sylvie

, p. 6401 - 6404 (2007/10/03)

Demetallation of tricarbonyliron diene complexes is rapidly achieved by treatment with freshly prepared Raney nickel. The ligands which are totally hydrogenated during the decomplexation are easily isolated in high yields, without racemization, if chiral.
