Recently it was shown that tert-butylcyanoketene reacts with optically enriched 1,2-cycbmmadiene to give a mixtureof the optically active epimeric cyclobutanones ( 3) and ( 2). The lack of knowledge of the optical purity of these produ~ts~ allowed the cons%eration of two mechanistic consequences whi

The structure and optical compensation of polymers having asymnetric carbon atoms in the main chain are discussed. When rectus (R) and sinister ( S ) isotactic ( it) polymers mix in a 1:1 ratio giving a racemic crystalline sample, three kinds of optical compensation can be considered; (a) optical co
Cycloaminoalkylnaphthalene 3 shows interesting opioid-like analgesic properties. It possesses two chiral centers and can exist as two racemic pairs and four diastereomers. Since the binding of opioids with receptors is stereoselective, it was important to have the two racemic pairs as well as the fo
