This article deals with the study carried out on the synthesis of 4-am
ino substituted trinems 1 starting from the key-intermediate -3-[(R)-1
-(t-butyldimethylsilyloxy)ethyl]-4-[(1'R, 2'S, 3'R)-1',2'-epoxycyclohe
x-3'-yl]azetidin-2-one 2. In particular, epoxide opening with various
amines and subsequent cyclization to the corresponding trinems were ex
plored. Their synthesis and antimicrobial activity are reported. Copyr
