An approach to the core skeleton of lancifodilactone F.

چکیده
Two cycloaddition reactions were utilized for the construction of the 5,6,7-tricyclic skeleton of lancifodilactone F and buxapentalactone. A [2+2] ketene cycloaddition reaction was first used to set their adjacent all-carbon quaternary centers at the 5,6-ring junction. An arene-olefin meta-photocycloaddition reaction was then used to install the 6- and 7-membered rings concurrently.

Construction of the 5,6,7-tricyclic skeleton of lancifodilactone F.
We report herein the synthesis of a fully functionalized B,C,D-ring system of lancifodilactone F. The key transformations involve an arene-olefin meta-photocycloaddition reaction and a palladium-catalyzed oxidative C-C cleavage reaction to establish its B,C-rings.

In this article, Imam Khomeini’s political theory is investigated with the Lakatos methodology. His methodology confirms the distinction between a hard core or the original skeleton of investments and experimental propositions confirms as a protective belt for the research program. Regarding this, the claim from this article is that if we understand the system of religious knowledge of Imam Kho...

متن کاملVentilated hollow core slab as a thermal mass strategy and its effect on thermal comfort; (case study: lotion college, England)
Thermal mass is the material's ability to store heat and release it after an amount of time and concrete is considered one of the best thermal mass material. Since concrete has been used widely in many building constructions, by considering the capability of concrete in terms of thermal mass, it is worthwhile to use this ability of concrete in order to build buildings more healthy and comfortab...
