steric-approach control

Control of @S05991@ of a reaction by @S06000@ towards attack of the @R05190@, which is directed to the less hindered face of the molecule. Partial bond making is strong enough at the @T06468@ for steric control to take place. This suggests that the @T06468@ should not be close to products.
