“…[1][2][3][4][5] Often, when such cyclohex-2-enones are needed, they are derived from naturally occurring sources, such as carvone, 6,7 pulegone, [8][9][10] sugars, 11 pinene, 12 quinic acid, 13,14 or quebrachitol. 15,16 A critical role in complex molecule construction relies on availability into specific optically pure targets along with reactions to elaborate and couple them.…”
