Highly Efficient and Diastereoselective Synthesis of (+)-Lineatin
摘要:
A linear sequence was used to synthesize (+)-lineatin in 14 steps and 14% overall yield from a homochiral 2(5H)-furanone. Key steps of this synthetic approach feature the diastereoselective construction of a cyclobutene through a photochemical [2 + 2] cycloaddition and a regiocontrolled oxymercuration reaction.

(±) - 33,7 - Trimethyl - 2,9 - dioxatricyclo[3.3.1.04,7]nonane 1 and (±) - 3,3,7 - trimethyl - 2,9-dioxatricyclo [4.2.1.04,7]nonane 2 were synthesized. The former was shown to be (±)-lineatin, an ambrosia beetle pheromone. A selective synthesis of (±)-lineatin was devised, which was modified to yield the both enantiomers of lineatin via optical resolution of an intermediate.
