Unusual thermolysis of aza­cyclic allene under microwave conditions: crystal structure of (3RS,3aSR,8RS,8aRS)-methyl 5,6-dimeth­oxy-3a,10-dimethyl-1-phenyl-3,3a,8,8a-tetra­hydro-3,8-(epimino­methano)­cyclo­penta­[a]indene-2-carboxyl­ate from synchrotron X-ray diffraction

The title compound, C25H27NO4 (I), the product of the unusual thermolysis of aza-cyclic allene methyl 10,11-dimeth-oxy-3,8-dimethyl-6-phenyl-3-aza-benzo[d]cyclo-deca-4,6,7-triene-5-carboxyl-ate, represents a bicyclic heterosystem and crystallizes in the monoclinic space group P21/c with three crystallographically independent mol-ecules in the unit cell… CONTINUE READING
