合成路线1
该中间体在本合成路线中的序号：(III)The reaction of cyclohexanone (I) with acrylonitrile (II) by means of pyrrolidine gives 3-(2-oxocyclohexyl)propionitrile (III), which is condensed with methoxymethyltriphenylphosphonium chloride (IV) in THF to yield the methoxymethylene derivative (V). The condensation of propionitrile (V) with 4-bromostyrene (VI) by means of n-BuLi ethyl ether affords the styryl ketone (VII), which is cyclized by means of triphenyl phosphite and O3 (or air, methylene blue and light) to provide trioxane (VIII) as a diastereomeric mixture that is separated by column chromatography. Finally, the vinyl group of the desired diastereomer (VIII) is oxidized with KMnO4 in acetone to afford the target compound.
