5- -2-methy!thio

The thermal cyclization of (methoxymethylthio)(3,4-difluorophenyl-amino)methylenemalonate (789, R = F, R1 = MeOCH2) by heating in diphenyl ether at 240°C for 5-10 min yielded 6,7-difluoro-2-(methoxy-methy thio)quinoIine-3-carboxyIate (790, R = F, R1 = MeOCH2 (87BRP2190376). [Pg.185]

Lithiation of the methyl of (methylthio)benzene followed by acylation with an acyl chloride and acidification to pH 4-5 yields benzothiophene in good yields, but when aroyl chlorides are used, the mixture has to be heated in benzene. An attempted dehydration of the secondary alcohol (87.4) with hydrobromic acid led to S-demethylation and cyclization. Similar treatment of the isomeric 2-(2-methy thio-4-nitrophenyl)-l-phenylethanol gave a high yield of 6-nitro-2-phenyl-2,3-dihydrobenzo[fi]thiophene [2653]. [Pg.564]

Trls(methy]thio)methyllithium, (CH3S)3CLi, (1) Mol. wt. 160.25. This anion was first reported by Seebach, who prepared it by reaction of n-butyllithium with tris(methylthio)methane. [Pg.210]

V-(3-Chloro-4-fluorophenyl )amino(mercapto)methylenemalonate (344) was reacted with 4-methoxybenzyl chloride in the presence of potassium carbonate in acetonitrile at ambient temperature for 3 hr to give AM3-chloro- 4 -fluorophenyl)amino[ (4-methoxybenzyl)thio]methy lenemalonate (345) in 81% yield (82EUP58392). [Pg.96]

Under these strong acid conditions, products from other rearrangements and acid cleavage reactions are sometimes found. For example, a mixture of 5-r-butyl-3-methyl-benzo[6]thiophene (the expected product), 6-f-butyl-3-methyIbenzo[6]thiophene and 3-methy benzo[6]thiophene was obtained on cyclization of p-t- butylphenylthioacetone with phosphorus pentoxide. During the cyclization of phenyl phenacyl sulfide to give a mixture of 2- and/or 3-phenylbenzo[Z ]thiophenes, small amounts of diphenyl disulfide and 5-pheny thio-3-phenylbenzo[6]thiophene were also formed (70AHC(11)177). [Pg.880]

The antifungal activity and the hydrophobicity are expressed as logarithmically converted reciprocals of MICs (mM) for the fungus E. chevalieri and logarithmically converted retention times from the ODS-HPLC analysis (column, LiChrosorb RP-8 (4.6 i.d. x 250 mm) mobile phase, water-acetonitrile-acetic acid (70 30 1) and detection, at 270 nm) of the compounds, respectively. The symbols denote the compounds grouped into (A), (B), and (C) in Table 5 B, 3-[(a-alkoxy)-a-methoxy]methyl derivatives ((A), alkoxy n-propoxy, n-butoxy, n-pentyloxy, n-hexyloxy, and n-heptyloxy) , 3-[(a-alkoxy)-a-methyl-thio]methyl derivatives ((B), alkoxy n-propoxy and n-butoxy) and A, 3-(alkoxy )methy-lene derivatives ((C), n-propoxy and n-butoxy). [Pg.1098]
