Abstract: We present ALMA observations towards two high-mass star forming regions. These reveal extended filamentary structures fragmenting into a number of dense cores. The detection of a multitude of lines from complex molecular species has permitted to study the physical and kinematic properties of three dense cores. Signposts of Keplerian rotation are identified and suggest the presence of disks rotating about stars with masses 4–18 . These results seem to confirm that B-type stars form via disk-mediated accretion, and set the stage for the quest for similar kinematical structures toward the most massive O-type stars.
