Strained Systems/Angle Strain

Complex molecules containing strained systems (e.g.  deviation from ideal bond angles, anti-Bredt olefins, etc.)

subtopics:  small rings (3 or 4 atoms, 27.5 – 26.3 kcal/mol strain energy), medium rings (8 – 11 atoms, 9.7 – 11.3 kcal/mol strain energy), anti-Bredt’s rule natural products (i.e. paclitaxel)
