31753-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31753-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31753-19:
(7*3)+(6*1)+(5*7)+(4*5)+(3*3)+(2*1)+(1*9)=102
102 % 10 = 2
So 31753-19-2 is a valid CAS Registry Number.

Identification of a crucial substructural unit for thromboxane A2 receptor binding

Corey,Su

, p. 2677 - 2680 (1990)

A stereospecific synthesis of the 9α,10α-epoxyprostanoic acid derivative 3, a potent and stable mimic of thromboxane A2, is described.

Chemical transformation of prostaglandin-A2: A novel series of C-10 halogenated, C-12 hydroxylated prostaglandin-A2 analogues

Ratnayake, Anokha S.,Bugni, Tim S.,Veltri, Charles A.,Skalicky, Jack J.,Ireland, Chris M.

, p. 2171 - 2174 (2006)

Synthesis of a novel class of C-10 halogenated and C-12 oxygenated prostaglandin-A2 derivatives (6a-6c) has been accomplished. (15S)-Prostaglandin-A2 (1), from the gorgonian Plexaura homomalla, served as the starting material for the synthesis. The absolute configuration was determined using NMR.

A Triply Convergent Total Synthesis of L-(-)-Prostaglandin E2

Donaldson, R. E.,Saddler, J. C.,Byrn, S.,McKenzie, A. T.,Fuchs, P. L.

, p. 2167 - 2188 (2007/10/02)

This paper details a versatile and efficient total synthesis of l-(-)-PGE2 (3).The key step is a triply convergent conjugate-addition/alkylation reaction involving the 1,4-addition of chiral vinyllithium reagent 7b to chiral vinyl sulfone D-47 to afford sulfone-stabilized anion , which is subsequently alkylated to produce the basic prostaglandin E2 skeleton 70.The synthesis of chiral vinyl sulfone D-47 involves a five step sequence with an enantioconvergent resolution process as one step and produces vinyl sulfone D-47 from readily available sulfide alcohol DL-11 in an overall yield of 36percent.The preparation of D-47 features two steps that utilize stereospecific SN2'reactions.The synthesis of l-(-)-PGE2 (3) involves a seven-step sequence from vinyl sulfone D-47 using mild conditions with an overall yield of 40percent and features an efficient peracetic acid oxidation of secondary amino acid 120 to oximino acid 121, which is, in turn, desulfonylated by 1,4-elimination of phenylsulfinic acid to generate a vinyl nitroso species that undergoes stereospecific 1,4-reduction by sodium borohydride to yield oxime 131.The hydrolysis of oxime 131 to l-(-)-PGE2 (3) using boron trifluoride and paraformaldehyde is the first reported high-yield method (84percent).This gives an overall yield for the synthesis of l-(-)-PGE2 (3) from racemic sulfide alcohol DL-11 of 14.5percent, including the resolution process.
