1. Passerini multicomponent reaction of indane-1,2,3-trione: an efficient route for the one-pot synthesis of sterically congested 2,2-disubstituted indane-1,3-dione derivatives
A reação de Passerini de indano-1,2,3-triona, isocianetos e derivados do ácido benzóico ocorre a temperatura ambiente, conduzindo a derivados estericamente congestionados de indano-1,3-diona 2,2-dissubstituídas em excelentes rendimentos. A reação é limpa, ocorre sob condições brandas e reações laterais não foram observadas.

2. Laser flash photolysis study of the reaction of 1H-benz[f]indane-1,2,3-trione with olefins
A fotoquímica de 1H-benz[f]indano-1,2,3-triona (1) em presença de olefinas, em solução de benzeno e a temperatura ambiente, foi examinada empregando a técnica de fotólise por pulso de laser. O estado excitado triplete de 1 (tau = 3 mis, lambda = 460 e 490 nm, em benzeno) é suprimido por olefinas contendo hidrogênio alílico com constantes de velocida

3. Aplicação de trinitrato de tálio na preparação de indanos e na síntese total do mutisiantol / Thallium trinitrate application in the preparation of indanes and in the total synthesis of mutisianthol
This thesis presents the first synthetic application of the methodology developed in our research group, which involves the ring contraction of 1,2- dihydronaphthalenes promoted by thallium trinitrate (TTN) to afford indane derivatives. The target molecule of the synthetic approach is Mutisianthol, a phenolic sesquiterpene, isolated from Mutisia homoeantha i

4. Orientation of intermediate nucleotide states of indane dione spin-labeled myosin heads in muscle fibers.
We have used electron paramagnetic resonance to study the orientation of myosin heads in the presence of nucleotides and nucleotide analogs, to induce equilibrium states that mimic intermediates in the actomyosin ATPase cycle. We obtained electron paramagnetic resonance spectra of an indane dione spin label (InVSL) bound to Cys 707 (SH1) of the myosin head,

5. Independent mobility of catalytic and regulatory domains of myosin heads
The recent determination of the myosin head atomic structure has led to a new model of muscle contraction, according to which mechanical torque is generated in the catalytic domain and amplified by the lever arm made of the regulatory domain [Fisher, A.

6. A spin label that binds to myosin heads in muscle fibers with its principal axis parallel to the fiber axis.
We have used an indane-dione spin label (2-[-oxyl-2,2,5,5-tetramethyl-3-pyrrolin-3-yl)methenyl]in dane-1,3-dione), designated InVSL, to study the orientation of myosin heads in bundles of chemically skinned rabbit psoas muscle fibers, with electron paramagnetic resonance (EPR) spectroscopy. After reversible preblocking with 5,5'-dithiobis(2-nitro-benzoic aci
