503-29-7, Name is Azetidine, molecular formula is C3H7N, belongs to isothiazole compound, is a common compound. In a patnet, author is Tsolomiti, Georgia, once mentioned the new application about 503-29-7, Safety of Azetidine.
Rearrangement of 5-benzoyl-3(2H)-isothiazol-3-ones to 6-benzoyl 2,3-dihydro-1,3-thiazin-4(2H)-ones
5-Benzoyl-3(2H)-isothiazol-3-ones 4 were converted to the corresponding isomeric 6-benzoyl-2-substituted-2,3-dihydro-1,3-thiazin-4(2H)-ones 13 by the following reaction sequence: the preparation of aroylpropionamides (3), the conversion of (3) to aroylisothiazolones (4), the protection, by ketalization, of the aroyl carbonyl group of (4), the transformation of isothiazolone ketals (11) to the corresponding thiazinone ketals (12) and finally the deketalization reaction to aroylthiazinones (13) in good overall yields.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 503-29-7. The above is the message from the blog manager. Safety of Azetidine.
