WebThe S(+)-carvone or R(−)-carvone obtained is converted to a solid semicarbazone derivative to remove any traces of limonene (Figure 2).7−11 Because of the restricted rotation about the C N bond, two possible diastereomers could form (Figure 2). Melting point determination helps to distinguish between α and β diastereomers.
