Ylides derived from 3-dimethylaminopropyltriphenylphosphonium salts react smoothly and stereospecifically with even hindered aldehydes to form Z-oletis which are easily converted to 1,3-dienes. In connection with research which recently led to the total synthesis of (+)-retigeranic acid, 1 we had
The kinetics of the nitric oxide catalyzed, homogeneous, gas-phase isomerizatioil of 1 ,trans-3,trans-5-heptatriene have been studied for temperatures ranging between 130Β°C and 241Β°C. The very clean reaction involves exclusive geometrical isomerization about the 5,6-x-bond. The observed rate constan
