Synthesis of 3,4-fused cycloalkanopyrroles by 1,3-dipolar cycloaddition
摘要:
The synthesis of a number of 3,4-fused cycloalkanopyrroles bearing substituents on the cycloalkane ring was accomplished by 1,3-dipolar cycloaddition. The yield of the cyclization appeared to depend on the base-sensitivity of the Michael acceptor, but the method is applicable across a broad range of cyclic alpha,beta-unsaturated ketone esters. Functional group transformations can be undertaken following pyrrole synthesis to increase the diversity of cycloalkanopyrroles accessible by this method. One pyrrole thus made is a diester of a conformationally-constrained analogue of porphobilinogen, the precursor of the natural tetrapyrroles. (C) 2011 Elsevier Ltd. All rights reserved.
