Toluenesulfenyl chloride has been prepared by the action of chlorine on a solution of -toluenethiol or />-tolyl disulfide in anhydrous carbon tetrachloride.2,3 Benzenesulfenyl chloride has also been obtained by the interaction of hydrogen chloride and N,N-diethylbenzenesulfenamide 4 and by reaction of benzenethiol with N-chlorosuccinimide.6 A comprehensive review dealing with sulfenyl halides and related compounds is available.6...

This paper thus clearly defined the possibility for a three-point attachment to provide for the differentiation of enantiomeric molecules. In support of the theory, they cited results on the action of epinephrine and related compounds. Cushny had reported that (— )-epinephrine is 12-15 times as active as (+ )-epinephrine. Easson and Stedman deduced that of the four groups around the chiral center, the hydrogen played no part in the drug-receptor attachment. Thus for (—)-epinephrine the complex could be represented as 7. With the (+ )-enantiomer the hydroxyl group cannot be positioned on the hydroxyl receptor. It was suggested that a less perfect combination was possible if the hydrogen were located on the normal hydroxyl... 

Urea is a well-known denaturant for proteins, and mechanistic investi tions have been carried out on the denaturing action of urea (97). Urea may interact with proteins through hydrogen bonding. To investigate this possibility in detail, interactions of urea and related compounds with cyclic peptide were investigated by means of NMR spectroscopy (92). 

A number of compounds related to 1 and 2 but with groups other than cyano have been reported. These include 55, 56, 57, and 58. The amides 56 and 57 were prepared by action of hydrogen...

H-Thiopyrans may occasionally be isolated from the reaction of 1,5-diketones, hydrogen sulphide, and acids, although they usually disproportionate under these conditions. Dienones give 2 T-thiopyrans with the same reagents. " [4 + 2] Cycloaddition of 3-dialkylaminovinyl aryl thiones with acrylic acid derivatives and related compounds afforded the 2fT-thiopyrans (10 R = H, OEt R = CN, CONHg, COMe, etc.). The intermediate 4-dialkylamino-A -dihydrothiopyrans were sometimes isolated. Factors affecting the addition were studied, and some reactions of (10) and the derived thiopyrylium salts were described. The preparation of the azido-thiopyrans (11 R = H or Ph) by the action of sodium azide on the thiopyrylium salts has been reported. Their thermolysis afforded substituted pyridines, thiophens, and sulphur, which were the decomposition products of the expected thiazepine intermediates.
