Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, which reinforce the learning of all students in general. This paper presents simple teaching resources that allow students with visual disabilities to solve problems of Organic Chemistry independently and on an equal footing with their nondisabled peers.
in recognition of their achievements in organic chemistry and their contributions in the development of the field in our country
AbstractIn this paper we report a simple "one pot" procedure to functionalized allyltin derivatives from 1-ethynylcyclohexene. Radical addition of trineophyltin hydride gives quantitatively to (Z,E)-1-(2-trineophylstannylvinyl)cyclohexene, a conjugated dienyl-stannane that, via a [4+2] cycloaddition reaction (Diels-Alder) with activated dienophiles, affords substituted bicyclic unsaturated products with specific stereochemistry and a trialkylstannyl group in allylic position. The Stille reaction of the allyltin compound enables the synthesis of aryl substituted bicyclic compounds in moderate to good yields (48-85%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
