We study if there is any relation between the fragmentation level in massive dense cores and the magnetic field properties. We also study whether molecular clouds are able to form extremely low-mass gravitationally unstable cores precursors of brown dwarfs. For these two goals we make use of millimeter interferometers such as the Atacama Large Millimeter/submillimeter Array in Chile, the Submillimeter Array in Hawaii or the Combined Array for Research in Millimeter-wave Astronomy in California.
