Synthesis of Organotin Substituted Tricyclic Macrodiolides
(Sociedade Brasileira de Química, 2015-10)
The radical addition of triorganotin hydrides, R3SnH (R=n-butyl, phenyl, neophyltin), to four unsaturated diesters of (11R,12R)-9,10-dihydro-9,10-ethaneanthracene-11,12-dimethanol leads to products of cyclohydrostannation ...
Polymer-Supported Stereoselective Synthesis of Tetrahydrobenzopyrazino-thiadiazinone Dioxides via N-Sulfonyl Iminiums
(American Chemical Society, 2014-02)
The stereoselective synthesis of 1,2,11,11atetrahydrobenzo[e]pyrazino[1,2-b][1,2,4]thiadiazin-3(4H)- one 6,6-dioxides on a solid support via tandem N-sulfonyl iminium ion cyclization, followed by nucleophilic addition is ...
Polymer-Supported Stereoselective Synthesis of Tetrahydro-2H-oxazolo[3,2-a]pyrazin-5(3H)-ones from N-(2-Oxo-ethyl)-Derivatized Dipeptides via Eastbound Iminiums
(American Chemical Society, 2013-02)
Polymer-supported N-(2-oxo-ethyl)-derivatized Ser/Thr/Cys-containing dipeptides were synthesized and subjected to acid-mediated tandem N-acylium ion cyclization−nucleophilic addition to yield tetrahydro-2H-oxazolo- ...

Valorização de monoterpenos de origem natural através de processos catalíticos tandem envolvendo a reação de hidroformilação catalisada por complexos de ródio
(Universidade Federal de Minas GeraisUFMG, 2013-05-17)
Rhodium-catalyzed tandem hydroformylation-acetalization of a series of r-menthenic terpenes, i.e., g-terpinene, terpinolene and limonene, has been studied in ethanol solutions in the presence of PPh3 or P(O-o-tBuPh)3 as ...
Synthesis of 1α,25-Dihydroxyvitamin D3 Analogues with α-Hydroxyalkyl Substituents at C12
(2013)
Convergent syntheses of three new analogues of 1α,25-dihydroxyvitamin D3 with α-hydroxyalkyl substituents at C12 (4a–c) are described. The A-ring and triene system of each analogue were assembled by a tandem Pd-catalysed ...
