  • Patent number: 5919956
    Abstract: A process for the manufacture of an optionally protected 4,8,8-trimethyl-1-oxaspiro?2.5!oct-4-en-6-ol (I) starting from protected 4-hydroxy-2,6,6-trimethyl-2-cyclohexen-1-one (II) comprises reacting the protected compound (II) with dihalomethyllithium and, if desired, cleaving off the protecting group from the thus-obtained protected 4,8,8-trimethyl-1-oxaspiro?2.5!oct-4-en-6-ol. The dihalomethyllithium can be produced in situ by reacting a dihalomethane with a lower alkyllithium in the presence of the compound of formula II. Preferably, protected (S)-4-hydroxy-2,6,6-trimethyl-2-cyclohexen-1-one is converted into protected (3S,6S)-4,8,8-trimethyl-1-oxaspiro?2.5!oct-4-en-6-ol in this manner. Both the starting material (II) and the end product (I) of the process in accordance with the invention are known, valuable intermediates for the manufacture of carotenoids.
