A synthesis of 6-tributylstannyl-3,4-dihydro-2H-pyrans via coupling of enol triflates with (Bu3Sn)(Bu)Culi·liCN

Enol triflates derived from 6- and 7-membered ring lactones (6 cases) react with (Bu3Sn)(Bu)CuLi·LiCN in THF at -78 °C to give the corresponding α-tributylstannyl cyclic enol ethers in 54-85% yield.

Pederin: The metallated dihydropyran approach. Stereoselective reduction of N-acylimidates via rhodium-catalysed hydroboration

A synthesis of the insect toxin pederin (1) based upon the union of metallated dihydropyran 8 with the oxamate ester derivative 9 is described. Noteworthy features include (a) a new method for the construction of metallated dihydropyrans which tolerates h
