DEVELOPMENT OF CONJUGATE ADDITION OF LITHIUM DIALKYLCUPRATES TO THIOCHROMONES: SYNTHESIS OF 2-ALKYLTHIOCHROMAN-4-ONES AND ADDITIONAL SYNTHETIC APPLICATIONS

Lithium dialkylcuprates undergo conjugate addition to thiochromones to afford 2-alkylthiochroman-4-ones in good yields.This approach provide an efficient and general synthetic approach to privileged sulfur-containing structural EYELASH AND EYEBROW DYE motifs and valuable precursors for many pharmaceuticals, starting from common substrates-thiochrom

This paper aims to offer an extra-phonological analysis for a purely phoneticphonological phenomenon: epenthetic glides in Taqbaylit.In this language, both epenthetic glides [j] and [w] may Accessories appear in specific contexts and are usually considered a hiatus-repairing strategy.We will discuss the different contexts where all types of glides

Given the high prevalence of gender violence among adolescents and youth, research has underscored the importance of preventing it from an early age.The literature has clarified that the prevention of gender violence requires the union of the language of desire and of ethics to promote egalitarian relationships as desirable.Nevertheless, there is a

American cutaneous leishmaniasis (ACL) presents distinct active clinical forms with different grades of severity, known as localised (LCL), intermediate (ICL) and diffuse (DCL) cutaneous leishmaniasis.LCL and BOXES DCL are associated with a polarised T-helper (Th)1 and Th2 immune response, respectively, whereas ICL, or chronic cutaneous leishmanias

Due to global events in recent years, applications for political asylum have increased, although the number of people granted asylum in the United States and elsewhere has declined.Physicians and other health care professionals can play a crucial role in the evaluation of individuals seeking asylum, since appropriately T-Shirts documented objective
