On the reaction of anthranilic acid with thionyl chloride : Iminoketene intermediate formation
It has been reported that sulfinamide anhydride is formed when anthranilic acid is treated with thionyl chloride under anhydrous conditions. Garin et al. reported that no sulfinamide anhydride was formed in the reaction of anthranilic acid with thionyl chloride. They reported that 2-(sulfinylamino) benzoyl chloride was formed, in accordance with an earlier observation, under the same reaction c...
متن کاملReaction of L-2-acetylamino-2-carbomethoxyethanesulfonyl chloride with ammonia.
The conversion of L-2-acetylamino-2-carbomethoxyethanesulfonyl chloride (I) to L-2-acetylamino-2-carbomethoxyethanesulfonamide (II) proceeds with considerable variability in yield We therefore investigated the nature of the by-product (s) of this reaction in order to prepare II in consistently high yields and with reproducible physical data. Compound II [m. p. 145°, [a] 54 2 8 ° (c 2, 95% ethan...
متن کامل2-Amino-4-tert-butyl-5-(4-chlorobenzyl)thiazol-3-ium chloride
The title compound, C(14)H(18)ClN(2)S(+)·Cl(-), crystallizes with two formula units in the asymmetric unit. The dihedral angles between the mean planes of the chloro-phenyl and thia-zole rings are 87.8 (2) and 88.0 (2)° in the two independent mol-ecules. In the crystal, the anions and cations are connected by N-H⋯Cl hydrogen bonds.

15 صفحه اول2 - ( tert - Butyl ) - 4 - phenyloxetane
The two geometric isomers of 2-(tert-butyl)-4-phenyloxetane have, for the first time, been prepared starting from the commercially available 4,4-dimethyl-1-phenylpentane-1,3-dione. The latter was reduced with NaBH4 to give a mixture of diastereomeric syn and anti diols which were then stereospecifically cyclized into the corresponding oxetanes with an overall yield for the two steps of 69.6%. T...
