Intramolecular additions of allylsilanes to conjugated dienones. A direct stereoselective synthesis of (.+-.)-14-deoxyisoamijiol
摘要:
A 16-step synthesis of (+/-)-14-deoxyisoamijiol is reported featuring an intramolecular addition of an allylsilane to a conjugated dienone to construct stereospecifically the dolastane skeleton.

cis-2,6-disubstituted tetrahydropyrans in good yields. Evidence suggests that InI, formed upon aldehyde (R1CHO) allylation in aqueous media, acts as a promoter for the silyl-Prins reaction with the second equivalent of added aldehyde (R2CHO). The preparation of cyclohexenyl-fused pyrans via this one-pot, three-component coupling process is presented, as is a short formal synthesis of (±)-centrolobine
