Synthesis of some new pyrimidines, thienopyrimidines and thiopyranopyrimidines

Isothiocyanate 1 reacted with enaminone 2 to give thioamide 3 that cyclized by sodium hydroxide to pyrimidine 4 but cyclized by bromine to give isothiazole 5, pyrimidine 4 was transformed into thiopyranopyrimidines 7, 9 or 11 upon respective reaction with benzaldehyde, maleic acid, or maleic anhydride. Aminative cyclization of 4 yielded isothiazolopyrimidine 13. Reaction of 4 and ethyl bromoacetate or phenacyl bromides afforded thienopyrimidines 15a-b respectively.

Regioselective lithiation and functionalization of 3-(benzyloxy)isothiazole: Application to the synthesis of thioibotenic acid

Direct functionalization of the 3-oxygenated isothiazole heteroaromatic parental system has not yet been reported in the literature. Here, we report the first regioselective lithiation of the 5-position of 3-(benzyloxy)isothiazole (4) using LDA in diethyl ether. The versatility of the methodology was explored by quenching with a variety of electrophiles to give the desired products 7a,b,d-g in 54-68% yield. Only benzoylation aiming at the synthesis of 7c was unsuccessful. Furthermore, a highly convergent synthesis of thioibotenic acid (1), the sulfur analogue of the neurotoxic natural product ibotenic acid, was carried out.

Hexamethyldisilathiane-based thionation of carbonyl compounds: A versatile approach to sulfur-containing heterocycles

Reactions of hexamethyldisilathiane (HMDST) with carbonyl compounds under the catalytic activity of CoCl2 center dot 6H(2)O or trimethylsilyltriflate lead to a simple and general access to thioaldehydes and thioketones, which could be isolated as their cycloadducts with dienes. The use of CF3SO3SiMe3 in reactions with cyclohexadiene allows a stereopredetermined access to either the endo- or the exo-isomer. Furthermore, on using P-silyl-substituted acetylenic ketones, a smooth access to acetylenic thioketones can be achieved. In reactions with aromatic and heteroaromatic o-azido aldehydes, the reactivity of HMDST may be finely tuned toward the synthesis of o-azido thioaldehydes, fused isothiazole ring systems, aromatic and heteroaromatic o-amino aldehydes, and o-amino thioaldehydes. HMDST proved also very efficient in thionating more intriguing substrates such as acylsilanes. Thus, thioacylsilanes, thioformylsilanes, unsaturated thioacylsilanes and -stannanes can be obtained in good yields. Ethylenic thioacylsilanes showed an interesting behavior leading to a general synthesis of functionalized dithiins. Finally, HMDST led also to the synthesis of bis(thioacylsilanes), which led to the formation of new silylated thiaheterocyclic systems.

Expanding a fluorescent RNA alphabet: synthesis, photophysics and utility of isothiazole-derived purine nucleoside surrogates

A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization. In addition to an adenosine and a guanosine mimic, analogues of the noncanonical xanthosine, isoguanosine, and 2-aminoadenosine were also synthesized and found to be emissive. Isothiazolo 2-aminoadenosine, an adenosine surrogate, was found to be particularly emissive and effectively deaminated by adenosine deaminase. Competitive studies with adenosine deaminase with each analogue in combination with native adenosine showed preference for the native substrate while still deaminating the isothiazolo analogues.
