14758-37-3 Usage

General Description

2-(methylsulfanyl)-1,3-dithiane is a chemical compound that consists of a dithiane ring with a methylsulfanyl group attached at position 2. It is commonly used as a building block in organic synthesis, particularly in the preparation of heterocyclic compounds. The presence of the dithiane group makes it a useful protective group for aldehydes and ketones, allowing for selective manipulation of these functional groups in complex molecule synthesis. Additionally, it can be used as a nucleophile in various reactions, making it a versatile reagent in organic chemistry. As a result, 2-(methylsulfanyl)-1,3-dithiane is an important and widely used compound in the field of chemical synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 14758-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,5 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14758-37:
(7*1)+(6*4)+(5*7)+(4*5)+(3*8)+(2*3)+(1*7)=123
123 % 10 = 3
So 14758-37-3 is a valid CAS Registry Number.

A convenient high yield synthesis of functional methacrylates via dethioacetalization. Synthesis of methacrylate S,S-acetal derivatives as intermediates

Caye, Florence,Sindt, Michele,Mieloszynski, Jean-Luc,Paquer, Daniel

, p. 197 - 220 (2007/10/03)

We describe a selective and efficient synthesis of a whole new class of functional methacrylates starting from S,S-acetals. Carbonyl compounds were regenerated from corresponding S,S-acetaIs using mercury (II) salts. According to this method, methacrylic

The invention finally relates to a cosmetic or pharmaceutcial composition which contains at least one compound of formula (I) in a suitable vehicle; the pharmaceutical composition according to the invention may be used for treating dermatological, rheumatic, respiratory or ophthalmological conditions.

Reactions of δ-valerolactone with lithio trithio-orthoformates

Yates, Peter,Seif-El-Nasr, Azza,Stanton, Jennifer,Krepinsky, Jiri J.

, p. 415 - 422 (2007/10/02)

δ-valerolactone (3), on treatment with tris(methylthio)methyllithium (7) followed by weakly acidic aqueous work-up, gave a tautomeric mixture of 1,1-bis(methylthio)-6-hydroxy-2-hexanone (8a) and tetrahydro-2-bis(methylthio)methyl-2-pyranol (8b).Under analogous conditions 3 reacted with tris(phenylthio)methyllithium (10) to form tetrahydro-3-(phenylthiocarbonyl)-2-pyranone (11).With 2-(methylthio)-1,3-dithian-2-yllithium (16) it gave a tautomeric mixture of 2-(5-hydroxy-1-oxopentyl)-2-(methylthio)-1,3-dithiane (17a) and 2-(tetrahydro-2-hydroxy-2-pyranyl)-2-(methylthio)-1,3-dithiane (17b).Treatment of 17 with methanol in the presence of acidic ion-exchange resin gave a mixture of 2-(5,6-dihydro-3-(methylthio)-2(4H)-pyranyl-1,3-dithiane (20), 2-(tetrahydro-2-methoxy-2-pyranyl)-1,3-dithiane (21), and 2-(tetrahydro-2-methoxy-(4-methylthio)-2-pyranyl)-1,3-dithiane (22).Similar treatment of 20 gave a mixture of 20, 21, and 22.Compound 21 was synthesized independently by similar treatment of 2-(tetrahydro-2-hydroxy-2-pyranyl)-1,3-dithiane (23).The origins of the anomalous products are discussed briefly.It is concluded that because of these anomalies the preparation of tetrahydro-2-hydroxypyran-2-carboxylic acid acetals and related glycosides via trithio-orthoformate derivatives can encounter difficulties, although dithioacetales may serve this purpose. Key words: 1,3-dithianes, α-hydroxy acids, δ-lactones, trithio-orthoformates.
