    Abstract: The present invention relates to a method for preparing lactams using heterogeneous catalysis by hydrogenating at least one compound of the following formula (I), where A is a radical of the following formula (I′) or (II′): —CH(R1)—CH(R2)— (I′); or —CH(R1)—CH(R2)—CH(R3)— (II′); where R1, R2 and R3 are, independently from each other, H, OH, an alkyl radical, or a cycloalkyl radical; and R is H or a straight or branched alkyl radical having 1 to 20, preferably 1 to 10, and more preferably 1 to 4 carbon atoms. Said method is carried out at a pressure of less than 60 bars, preferably 10 to 50 bars, in the presence of a solid hydrogenation catalyst including at least two metals selected from the group of noble metals and transition metals, and an inert substance used as a support, wherein said compound of formula (I) can be used alone or as part of a mixture.
