Second parent adoption e omogenitorialità
No full textThe Author analyses the decision from the European Court of Human Rights, Grand. Chamber, 19-2-2013, n. 19010/07 (X. vs. Austria), according to which the stable relationship of a cohabiting same-sex couple falls within the notion of "family life" pursuant to art. 8 of the ECHR read in conjunction with art. 14 ECHR, in the same way that a couple of different sexes would fall into the same situation. The Austrian law (art.182 ABGB) which allows, with the consent of the other natural parent of the minor, the adoption of the partner's child to unmarried couples, but not to same-sex couples, infringes the art. 14 ECHR in combination with art. 8 of the ECHR, because in this case the difference in treatment, being based only on sexual orientation, turns out to be unjustified. The Author criticizes some aspects of the reasoning of the sentence but investigates what could be the remedies offered by Italian law in similar cases
Insect pheromones. Stereoselective reduction of alpha- or omega-alkynols to the corresponding (E)-alkenols by lithium tetrahydroaluminate
No full textRedn. of RC≡C(CH2)nOH (I; n, R given; 7, MeCHEt(CH2)4; 2, hexyl; 6, Bu; 6, octyl) with LiAlH4 in diglyme-THF gave 85-94% E-RCH:CH(CH2)nOH (II). I (n, R given; 7, MeCHEt(CH2)4; 6, Bu; 6, octyl) were prepd. by reaction of RC≡CLi with the resp. (tetrahydropyranyloxy)iodoalkane. The acetate of II (R = Bu, n = 6) is the sex pheromone of the false codling moth, Argyroploce leucotreta
Insect pheromones. Synthesis of chiral sex pheromone components of several species of Trogoderma (Coleoptera: Dermestidae)
No full textThe (S)-enantiomers of (Z)- and (E)-14-methyl-8-hexadecen-1-ol, 1 and 4, respectively, and of (Z)- and (E)-14-methyl-8-hexadecenal, 6 and 7, respectively, which are sex pheromone components of dermestid beetles, have been synthesized in high optical purity starting from optically pure (S)-2-methyl-1-butanol. The preparation of 1 has been carried out using a new general method for reducing stereoselectively and in high yield ω-alkynols to the corresponding (E)-alkenols. The rotatory power of optically pure 1, 4, 6 and 7 has been established
Synthesis of natural and unnatural cytotoxic (Z)-4-aryl-5-[1-(aryl)methylidene]-3-halo-2(5H)-furanones and a precursor to nostoclides I and II

No full textFunctionalized imidazole derivatives in- clude compounds that are known to possess a broad range of significant biological properties or are im- portant templates in medicinal chemistry. In the light of the importance of these heteroaromatic com- pounds a great deal of attention has been given to their synthesis and, in the past years, a number of methods has been described in the literature allow- ing for the construction of the heteroaromatic core of these substances by cyclization protocols. Howev- er, in recent years, much more attention has been fo- cused on the design and development of efficient protocols that are based on the selective functionali- zation of the imidazole ring at the N-1, C-2, C-4 or C-5 position via transition metal-catalyzed reactions and enable the synthesis of imidazole derivatives, in- cluding bioactive and/or naturally occurring com- pounds, which cannot be accessed by other means. This critical review with 439 references covers devel- opments in this hot area of research up to July 2009 and includes a description of synthetically important, regioselective transition metal-catalyzed Csp2-N, Csp-N, Csp3-N, Csp2-Csp2, and Csp-Csp2 bond form- ing methods, their applications, and limitations

No full textCoupling reactions between 2- or 3-thienylmagnesium bromide and dibromothiophenes in the presence of catalytic amts. of PdCl2[1,1'-bis(diphenylphosphino)ferrocene] gave 48-85% of three isomers of terthiophene as well as several bromobithiophenes. Thiophene esters I (R = H, 2-thienyl, 3-thienyl) were prepd. by Pd-catalyzed ethoxycarbonylation of bromothiophenes II under mild conditions. A short synthesis of naturally occurring (propynyl)bithienylcarboxylic acid III, from 2-thienylmagnesium bromide using Pd-catalyzed reactions, is reported
