WebMar 11, 2009 · The transformation of compounds 4 and 8 to the tricyclic aminonitriles 9 and 10 involves a dimerization step followed by a pyrrole cyclization. The tert -butyl ester derivatives 4d and 8d upon treatment with sodium hydride underwent a Thorpe-Ziegler cyclization to provide enaminoesters of fused 1,3-thiazines ( 16 and 17 , respectively) as … WebThe pressure in the dimerization zone is normally maintained in the range of 70 to 600 psig, preferably 400 to 600 psig, to maintain a liquid phase hydrocarbon operation. When conducting the dimerization reaction in the vapor phase higher pressures of 600 to 1,200 psig are preferred to'sustain a dense phase operation.
