✦ Synopsis

On the CD of six-1) and seven-membered2)lactams it has been reported that the ring chirality might determine the CD sign. However these CD rules has been derived from CD of the lactams in which their ring conformations were fixed with ring fusion and had no heteroatom substituents at Ca. In another report we revealed that in five-membered lactams 3) as well as Y-lactones 4) the CD sign and magnitude might be determined by two factors: (1) configuration at Cc and (2) ring chirality and their molar ellipticities might be addition of the two effects. The effect of Ca configuration is considered as an extention
