Isoprenoid Chain Elongations by Claisen Rearrangements Using Acetals as Precursors of Vinyl Ethers
Baeckstroem, Peter,Li, Lanna
, p. 6521 - 6532 (1991)
Claisen rearrangements of allyl vinyl ethers, formed in situ by the acid catalyzed reaction of dimethyl acetals of acetaldehyde, acetone and isopropenyl methyl ketone with different types of allylic alcohols, have been compared.The primary, secondary and tertiary allylic alcohols used in the investigation were selected to serve as models for isoprenoid synthesis.The basis for two feasible methods that can be iterated to create isoprenoid chains has been investigated.

Epoxyolefin cyclizations have attracted considerable interest due to their importance in biosynthetic pathways. Bismuth trifluoromethanesulfonate as well as several other metal triflates are shown to be highly effective (0.1 mol %) catalysts for the cycli

Treatment of appropriately substituted 5,9-diene, 5,9,13-triene and 5,9,13,17-tetraene phenoselenyl esters, e.g. 1a, 9 and 14, with Bu3SnH-AIBN is shown to lead to linear and angular six-ring fused polycycles, viz 2, 11 and 15 respectively, via
