A cascade radical-mediated Diels-Alder reaction with the iododienynone 16b produced the tricyclic ketone 17 (22%). By contrast, treatment of the substituted furans 36 and 47 with Bu3SnH-AIBN, instead led to the tetracycles 44 and 58 respectivel

A polycyclic carbapenem compound of the formula (Ia'), (Ib') or (Ic') STR1 [wherein COOR2 is a carboxy group which may be esterified; Ra' is --(CH2)m --Ka --(CH2)n --Ua' ; J is O or S; Rb' is --(CH2)m --Kb --(CH2)n Ub' ; J' is O, S or CH2 ; Rc' is --(CH2)m --Kc --(CH2)n --Uc', --(CH2)m --Kd --(CH2)n --Ud or a pair of groups, one of which is a hydroxy group, with the other being a hydroxzy group or an alkylsulfonylamino group, which may be substituted, in the position ortho to the first-mentioned hydroxy group] or a salt thereof are useful as an antibacterial agent.
