  Complex organic molecules have been observed for decades in the interstellar
medium. Some of them might be considered as small bricks of the macromolecules
at the base of terrestrial life. It is hence particularly important to
understand organic chemistry in Solar-like star forming regions. In this
article, we present a new observational project: SOLIS (Seeds Of Life In
Space). This is a Large Project at the IRAM-NOEMA interferometer, and its scope
is to image the emission of several crucial organic molecules in a sample of
Solar-like star forming regions in different evolutionary stage and
environments. Here, we report the first SOLIS results, obtained from analysing
the spectra of different regions of the Class 0 source NGC1333-IRAS4A, the
protocluster OMC-2 FIR4, and the shock site L1157-B1. The different regions
were identified based on the images of formamide (NH2CHO) and cyanodiacetylene
(HC5N) lines. We discuss the observed large diversity in the molecular and
organic content, both on large (3000-10000 au) and relatively small (300-1000
au) scales. Finally, we derive upper limits to the methoxy fractional abundance
in the three observed regions of the same order of magnitude of that measured
in few cold prestellar objects, namely ~10^-12-10^-11 with respect to H2
molecules.
