174953-30-1 Usage

General Description

The chemical 1,3,2-Dioxathiolane, 4-methyl-, 2,2-dioxide, (4S)-, also known as methyl dioxanone, is an organic compound with the molecular formula C5H8O4S. It is a cyclic sulfite with a heterocyclic ring containing oxygen and sulfur atoms. This chemical is used as a reactant in organic synthesis and as a component in the production of pharmaceuticals, agrochemicals, and other specialty chemicals. It is a colorless liquid with a pungent odor and is considered to be potentially hazardous if ingested, inhaled, or in contact with skin or eyes.

Check Digit Verification of cas no

The CAS Registry Mumber 174953-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,9,5 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174953-30:
(8*1)+(7*7)+(6*4)+(5*9)+(4*5)+(3*3)+(2*3)+(1*0)=161
161 % 10 = 1
So 174953-30-1 is a valid CAS Registry Number.

Expedient synthesis of (-)-(1S, 2R)-allonorcoronamic acid

Hercouet, Alain,Bessieres, Bernard,Le Corre, Maurice

, p. 283 - 284 (1996)

The title amino acid was synthesized in enantiomerically pure form, starting from (S)-(+)-1,2-propanediol 2 in three steps, by condensation of cyclic sulfate 3 with methyl benzylideneglycinate.

Combinatorial synthesis of functionalized chiral and doubly chiral ionic liquids and their applications as asymmetric covalent/non-covalent bifunctional organocatalysts

supporting information; experimental part, p. 567 - 576 (2008/10/09)

A facile combinatorial strategy was developed for the construction of libraries of functionalized chiral ionic liquids (FCILs) including doubly chiral ionic liquids and bis-functional chiral ionic liquids. These FCIL libraries have the potential to be use

Propylene glycol cyclic sulfate as a substitute for propylene oxide in reactions with acetylides

Bates, Roderick W.,Maiti, Tushar B.

, p. 633 - 640 (2007/10/03)

Lithium acetylides react cleanly with propylene glycol cyclic sulfate to give, after acidic hydrolysis, homopropargylic alcohols in good yield. The benzyl and TBDPS protecting groups are stable to these conditions, but the THP, TBS, acetal and orthoester groups are not. The readily available (S)-cyclic sulfate gives the (S)-alcohol without loss of stereochemical integrity.
