STUDIES ON ORGANOPHOSPHORUS COMPOUNDS V1-4. REACTION OF 2,4-BIS(4-METHOXYPHENYL)-1,3,2,4-DITHIA DIPHOSPHETANE-2,4-DISULFIDE WITH CYCLIC AND HETEROCYCLIC KETONES
摘要:
Cyclic ketones 2 and 8a,b reacted with Lawesson's reagent (1) in different molar ratios to give the oxathiaphosphole (4), the disulfide 7 and the dithiones 9a,b. N-Methyl barbituric acid (10b) reacted with LR to produce the enethiole 11 and the sulfide 12. Pyrazolone derivatives 13 and 17 reacted with LR in different molar ratios to form the corresponding products 15, 16 and 19. Rohdanine (20) reacted with LR to give the enethiole 22 and the disulfide 23.
The present invention relates to a compound represented by a formula (I): wherein X is a group represented by or the like; Y is a group represented by or the like; and Ar
1
is a group represented by or a pharmaceutically acceptable salt thereof.
The present invention relates to a compound that is useful for treatment of, for example, hypertension, arteriosclerosis, bulimia and obesity because of having an antagonistic action to a neuropeptide Y receptor and is represented by formula (I)
[wherein R
1
represents hydrogen, cyano, or the like;
R represents a group represented by formula (II);
X
1
represents C
1-4
lower alkylene or the like; X
2
represents lower alkylene or the like; and Het represents a 5-membered heteroaromatic ring that has at least one nitrogen atom and, in addition, one or two hetero atoms selected from the group consisting of nitrogen, sulfur and oxygen atoms]
or to a pharmaceutically acceptable salt thereof.
The present invention relates to a compound represented by a formula (I): wherein X is a group represented by or the like; Y is a group represented by or the like; and Ar1 is a group represented by or a pharmaceutically acceptable salt thereof.
