Chemical Research Letters, April 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 581-96-4, Name is 2-(Naphthalen-2-yl)acetic acid, molecular formula is C12H10O2, Formula: C12H10O2, belongs to isothiazole compound, is a common compound. In a patnet, author is Clerici, F, once mentioned the new application about 581-96-4.
3-Diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide(1) was made to react with arylalkyl- and arylazides 2. Cycloadducts 3, which could he isolated in some cases, afforded N-arylalkyl or N-aryl-thiadiazabicyclo[3.1.0]hexene derivatives 4 through N-2-elimination. Thermal rearrangements of N-aryl- and N-beta-phenylethyl substituted compounds 4b-e, produced derivatives of 1,2-thiazete 1,1-dioxide 5, 1,2,6-thiadiazine 1,1-dioxide 6 and pyrazole 7. The reaction can be optimized to afford compounds 6 in synthetically useful yield. In the case of N-benzyl-thiadiazabicyclo[3.1.0]hexene derivative 4a the different substitution on the aziridine nitrogen produced a different reaction course, affording the thiadiazine derivative 6a and the pyrimidine derivative 8.
