An Unexpected Trimethylstannylpyrrole from a Stannylated Derivative of Tosylmethyl Isocyanide (TosMIC) and Chalcone
摘要:
The structure of the title compound, tert-butyl 3-benzoyl-4-phenyl-2- (trimethylstannyl)pyrrole-N-carboxylate, [Sn(CH3)(3)(C22H20NO3)], is one of the first in which the stannyl group is attached to a C atom of the pyrrole ring, There appears to be an intramolecular interaction between the Sn atom and the carbonyl O atoms of both the benzoyl and the tert-butoxycarbonyl substituents. The compound was prepared by a base-induced cycloaddition of a stannylated derivative of tosylmethyl isocyanide to chalcone.
