Asymmetric synthesis of 2-alkyl-4-hydroxycyclohex-2-en-1-ones by scandium(III) triflate-catalyzed fragmentation of 2-alkyl-3-iodo-1-oxocyclohexan-2,4-carbolactones
摘要:
Fragmentation of (2S,3S,4S)-2-allyl-3-iodo-1-oxocyclohexan-2,4-carbolactone to (4S)-2-allyl-4-hydroxy-cyclohex-2-en-1-one, a chiral building block of (-)-platensimycin, proceeded efficiently by using scandium(III) triflate in DMF-H2O (1:3) at 100 degrees C.
