Sulfur analogs of psychotomimetic agents. 2. Analogs of (2,5-dimethoxy-4-methylphenyl)- and of (2,5-dimethoxy-4-ethylphenyl)isopropylamine
摘要:
The two thio analogues of each of the well-known psychotomimetic drugs DOM [(2,5-dimethoxy-4-methylphenyl)isopropylamine] and DOET [(2,5-dimethoxy-4-ethylphenyl)isopropylamine] have been synthesized and pharmacologically evaluated in man. The 5-thio isomers are more potent as psychotomimetic agents than the 2-thio isomers but still represent a drop of an order of magnitude in potency from the sulfur-free counterparts. The dithio analogue of DOM was synthesized and found to be without central activity at a dosage of approximately 50 times the mean effective dose of DOM.

The utilization of DMSO or Ph2SO/(COBr)2 or (COCl)2 for the bromination or chlorination of arenes has been explored. Notably, monobromination of activated arenes can be achieved with high regioselectivity using the combination of dimethyl sulfoxide and oxalyl bromide. Bromodimethylsulfonium bromide generated in situ was proposed to be the active species for bromination. In contrast, the practicality
