Conclusions In summary (Fig. 46), in simple systems, the cycloheptatriene is generally
favoured over the norcaradiene, due to relief of ring strain. However, through careful choice …

Bridge-containing segments exist in numerous natural products and active pharmaceutical
ingredients (API) and intermediates, creating more structural complexity. In addition, bridge …

Although theexistence of singlet molecular oxygen has been recognized since 1924, 1 its
