  Tandem synthesis and in vitro antiplasmodial evaluation of new naphtho[2,1-d]thiazole derivatives

  摘要：

  A series of naphtho[2,1-d]thiazoles was prepared in good yields under microwave irradiation with an original protocol combining tandem direct arylation and intramolecular Knoevenagel reaction on 1,3-thiazole derivatives. Antiplasmodial evaluation of this series highlighted two hit compounds (compounds 11 and 13) displaying promising in vitro activity on the multiresistant K1 Plasmodium falciparum strain. Structure-toxicity and structure activity relationships are also discussed and reveal the importance of the R-1 and R-4 substituents of the naphthyl moiety for the biological profile of the series.

  Tunable regioselectivity associated with the reaction of 2,3-dihalo-1-(phenylsulfonyl)-1-propenes with ambident nucleophilic reagents

  摘要：

  2,3-Dihalo-1-(phenylsulfonyl)-1-propenes, obtained by the addition of bromine or iodine onto (phenylsulfonyl)propadiene, were found to exhibit interesting reactivity as both mono- and dielectrophiles, with the mode of reactivity depending upon the nature of the nucleophile as well as the reaction conditions. Thus, amines or thiophenols smoothly effected substitution at the allylic site, while sodium methoxide reacted at the vinylic position through an addition-elimination process. In the realm of ambident nucleophiles, beta-dicarbonyl compounds in a medium of NaH/tert-butoxide/THF gave 2-alkyl-3-acyl-4-[(phenylsulfonyl)methyl]furans, produced by initial allylic S(N)2 displacement followed by 5-exo-trig cyclization. Conversely, such beta-dicarbonyls in a methoxide/methanol system yielded 2-alkyl-4-[(phenylsulfonyl)methyl]furans, where reaction proceeds by initial addition-elimination on the vinyl sulfone moiety. In contrast, silyl enol ethers in the presence of silver tetrafluoroborate resulted in products derived from S(N)2 displacement at the allylic site. Thioamides could be used to form 2-substituted thiazoles by initial allylic displacement by the sulfur atom followed by an addition-elimination reaction. Thus, a variety of compounds were prepared from 2,3-dihalo-1-(phenylsulfonyl)-1-propenes by the proper choice of reagents and reaction conditions.
