2-Acetamido-4-methylthiazole-5-sulfonyl chloride (cas: 69812-29-9) belongs to thiazole derivatives. The thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Recommanded Product: 69812-29-9

A novel route to 4-aryl-5,6-dihydro-1,2-oxathiin-2,2-dioxides and related heterocyclic systems was written by Bonfand, Eric;Motherwell, William B.;Pennell, Andrew M. K.;Uddin, Muhammed K.;Ujjainwalla, Feroze. And the article was included in Heterocycles in 1997.Recommanded Product: 69812-29-9 This article mentions the following:

The addition of a tributylstannyl radical to arene and heteroarene sulfonate esters of homopropargyl alcs. triggers a sequence of [1,6] ipso-substitution followed by 6-endo addition and elimination to yield unusual 4-aryl-5,6-dihydro-1,2-oxathiin-2,2-dioxides and related heterocyclic systems. E.g., addition of AIBN and Bu3SnH to 4-MeC6H4SO2NMeCH2CH2CCH gave 15% 1,2-thiazine-S,S-dioxide I and 8% 4-MeC6H4C(:CH2)CH2CH2NHMe. In the experiment, the researchers used many compounds, for example, 2-Acetamido-4-methylthiazole-5-sulfonyl chloride (cas: 69812-29-9Recommanded Product: 69812-29-9).
