16895-58-2 Usage

General Description

Thiochroman-3-one is a chemical compound with the molecular formula C9H8OS. It is a heterocyclic compound that contains a sulfur atom and a carbonyl group. Thiochroman-3-one is a derivative of thiochroman, which is a bicyclic organic compound. It has a distinct aroma and is used in the fragrance industry to create musky, amber, and woody scents. Thiochroman-3-one has also been studied for its potential pharmacological properties, including its anti-inflammatory and antitumor activities. Its chemical structure and properties make it an important building block for the synthesis of various pharmaceuticals and other organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 16895-58-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,9 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16895-58:
(7*1)+(6*6)+(5*8)+(4*9)+(3*5)+(2*5)+(1*8)=152
152 % 10 = 2
So 16895-58-2 is a valid CAS Registry Number.

Carbonyl 1,2-transposition through triflate-mediated a-amination

Wu, Zhao,Xu, Xiaolong,Wang, Jianchun,Dong, Guangbin

, p. 734 - 740 (2021/11/16)

To date, it remains challenging to selectively migrate a carbonyl oxygen within a given molecular scaffold, especially to an adjacent carbon. In this work, we describe a simple one- or two-pot protocol that transposes a ketone to the vicinal carbon. This approach first converts the ketone to the corresponding alkenyl triflate, which can then undergo the palladium- and norbornene-catalyzed regioselective a-amination and ipso-hydrogenation enabled by a bifunctional hydrogen and nitrogen donor. The resulting "transposed enamine" intermediate can subsequently be hydrolyzed to produce the 1,2-carbonyl-migrated product. This method allows rapid access to unusual bioactive analogs through late-stage functionalization.

Synthesis of the 5-Thiorotenoid System from Thiochroman-3-one

Gabbutt, Christopher D.,Hepworth, John D.,Heron, B. Mark

, p. 3015 - 3018 (2007/10/02)

Base-induced cyclisation of the diketones 10 (X = H or F), prepared in a two-step sequence from thiochroman-3-one, affords 6H,12H-benzothiopyranobenzopyran-12-ones 11.Reduction with diisobutylaluminium hydride affords a separable mixture of t

Metalation reactions XIII. The reactions of electrophiles with the dilithiated species 1-(α-lithiomethyl)-2-benzene

Cabiddu, S.,Floris, C.,Gelli, G.,Melis, S.

, p. 1 - 10 (2007/10/02)

Direct dimetalation of 1-methyl-2-(methylthio)benzene (1) gives the dilithiated species (2) in good yield, which can be used to introduce substituents into the thiomethyl and methyl groups.Species 2 can react also with a variety of dichlorosilanes and dichlorostannanes, and with sulphur chloride, to yield derivatives of 1,3-benzothiasilin, 1,3-benzothiastannin and 1,3-benzodithiin respectively.Reaction of 2 with tetrachlorosilane yields a spirocyclic silicon compound, while reaction with benzoyl chloride yields a derivative of 1-benzothiopyran.
