WebThe name of the first molecule is (R)-4-methylcyclohexene. The double bond gets priority in the naming, and the numbers must include both alkene carbon atoms. So C-1 is at the bottom, C-2 is at the 4-o'clock position, and the methyl group is on C-4. The name of the second molecule is (S)-3-bromo-3-chloro-2-methylpentane. WebThe catalytic addition of alkenes and amines (hydroamination) typically provides α- or β-amino stereocenters directly through C-N or C-H bond formation. Alternatively, desymmetrization reactions of symmetrical aminodialkenes or aminodialkynes provide
