Cyclizations of acetoxydienes 1 with Pd(PPh3)4/Et2Zn (0.05/4-5 mol-equiv.) in Et2O at reflux, followed by either protonation, iodination or cyanation, provide cis-disubstituted cyclopentanes and pyrrolidines 5,
CATALYTIC INTRAMOLECULAR 2-(4-ALKENYL)ALLYLPALLADIUM INSERTIONS
Oppolzer, Wolfgang,Swenson, Rolf E.,Gaudin, Jean-Marc

Pd(O)-catalyzed cyclizations of 1-acetoxy-2-methylene-6-heptenes(34, 1819) are consistent with a allylpalladium/olefin insertion involving a metal-transfer to the distal alkene terminal.Cyclization 78 exemplifies a new stereocontrolled access to
