FURANS IN SYNTHESIS 4. SILYL FURANS AS BUTENOLIDE EQUIVALENTS
The preparation and utilization of butenolide anion equivalents 5 and 6 in alkylation sequences is described.Treatment with CH3CO3H unmasks a latent butenolide moiety providing a general route to 3- and 4-alkyl 2(5H)-furanones.
Cyclialkylations of Conjugated Dienones with Furans
Fused tricyclic compounds with the salient features of the guaianolides and the pseudoguaianolides were prepared using a furan-based cyclialkylation strategy.
