250138-59-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 250138-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,1,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 250138-59:
(8*2)+(7*5)+(6*0)+(5*1)+(4*3)+(3*8)+(2*5)+(1*9)=111
111 % 10 = 1
So 250138-59-1 is a valid CAS Registry Number.

Construction of an enantiomerically pure 6-substituted 3,5-syn-dihydroxyhexanoic acid system by an enantioselective deprotonation strategy: Formal synthesis of an antiobesity agent, (-)-tetrahydrolipstatin

Honda,Endo,Ono

, p. 1545 - 1548 (2000)

Preparation of 6-substituted 4-hydroxytetrahydro-2H-pyran-2-one (12), a key intermediate for the synthesis of (-)-tetrahydrolipstatin, was achieved in an optically pure form by employing an enantioselective deprotonation reaction of the prochiral bicyclic

Enantioselective route to -silyl - Keto esters by organocatalyzed regioselective Michael addition of methyl ketones to a (silylmethylene)malonate and their use in natural product synthesis

Chowdhury, Raghunath,Ghosh, Sunil K.

, p. 1936 - 1945 (2011/07/31)

The direct Michael addition of alkyl methyl ketones through the acetyl methyl terminal to diethyl {[dimethyl(phenyl)silyl]methylene}malonate was catalyzed by the (S)-N-(pyrrolidin-2-ylmethyl)pyrrolidine/trifluoroacetic acid combination with high yield and excellent regio- and enantioselectivity. The ketone adducts can easily undergo de-ethoxycarbonylation to give β-silyl-δ keto esters with excellent synthetic potential. This has been demonstrated by the synthesis of a suitably substituted β-silyl-δ ester as an advanced intermediate for a chiral hydroxylated pyrrolidine natural product, (+)-preussin. Silicon-controlled diastereoselective reduction of the ketone functionality of β-silyl- δesters followed by lactonization of the resulting hydroxy esters gave disubstituted -valerolactones. Advanced intermediates for the antipodes of natural products, namely (+)-massoialactone and (+)-mevinolin analogue, and natural products, namely (-)-tetrahydrolipstatin and (+)-5-hexadecanolide, have been achieved.

A stereoselective synthesis of (-)-tetrahydrolipstatin

Ghosh, Arun K.,Liu, Chunfeng

, p. 1743 - 1744 (2007/10/03)

A stereoselective synthesis of (-)-tetrahydrolipstatin has been accomplished utilizing olefin metathesis of an acrylate ester as the key step.
