Eine einfache und flexible Synthese von Pyrrolen ausα,β-ungesättigten Sulfonen
摘要:
The addition of alkyl isocyanoacetates and isocyanoacetonitrile to alpha,beta-unsaturated sulfones affords a convenient and broad access to pyrroles with unusual substitution patterns (see Scheme 2). The alpha,beta-unsaturated sulfones required as starting materials are easily obtained from different olefines.
The addition of alkyl isocyanoacetate to α,β-unsaturatedsulfones, which are easily obtained from olefins, affords a convenient access to pyrroles with unusual substitution patterns.
