133760-99-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133760-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,6 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133760-99:
(8*1)+(7*3)+(6*3)+(5*7)+(4*6)+(3*0)+(2*9)+(1*9)=133
133 % 10 = 3
So 133760-99-3 is a valid CAS Registry Number.

Synthesis and Diels-Alder reactions of t-butyl and t-butyl, methyl (S)s-2-p-tolylsulfinylmaleates, chiral synthetic equivalents of monoalkyl and mixed dialkyl acetylenedicarboxylates

Alonso,Carretero,Ruano

, p. 947 - 950 (1991)

The reaction of t-butyl p-tolylsulfinylacetate with glyoxylic acid yielded maleate monoester 1, whose methylation afforded asymmetric diester 2. Conditions in which 1 and 2 react with cyclopentadiene exhibiting high facial and endo selectivities are reported.

SYNTHESIS AND DIELS-ALDER REACTIONS OF HOMOCHIRAL 2-SULFINYLMALEATES WITH CYCLOPENTADIENE

Alonso, Ines,Cid, M. Belen,Carretero, J. Carlos,Ruano, Jose L. Garcia,Hoyos, Miguel A.

, p. 1193 - 1207 (2007/10/02)

Enantiomerically pure 2-p-tolylsulfinylmaleates 1, 2 and 3 have been readily prepared by Knoevenagel reaction between (S)-menthyl p-toluenesulfinate and glyoxylic acid.Their asymmetric Diels-Alder reactions with cyclopentadiene have been studied under a wide range of uncatalyzed and catalyzed conditions and the stereochemical results have been explained by assuming a steric control approach, in term of S-cis or S-trans favoured conformations.Uncatalyzed Diels-Alder reactions of 1 and some Lewis acid catalyzed Diels-Alder reactions of 2 show high facial and endo selectivities.The facial selectivity of dienophile 2 highly depends on the Lewis acid, whereas reactivity of 1 and 3 is very sensitive to the solvent.These sulfinylmaleates 1, 2 and 3 act as synthetic equivalents of chiral acetylenedicarboxylates in Diels-Alder reactions after basic elimination of the sulfinylic moiety in the resulting adducts.
