A chemoenzymatic cascade process for the sustainable production of pyrroles has been developed. Pyrroles were synthesized by exploiting the previously unexplored aromatizing activity of monoamine oxidase enzymes (MAO-N and 6-HDNO). MAO-N/6-HDNO whole cell biocatalysts are able to convert 3-pyrrolines into pyrroles under mild conditions and in high yields. Moreover, MAO-N can work in combination with the ruthenium Grubbs catalyst, leading to the synthesis of pyrroles from diallylamines/-anilines in a one-pot cascade metathesis-aromatization sequence.

A general route to N-alkyl pyrroles by reacting aromatic, heteroaromatic or aliphatic aldehydes with 4-hydroxyproline in ionic liquid under neutral condition was developed. The ionic liquid can be readily recovered and reused for up to 5 reaction cycles without any effect on the yield of the product formed. The utility of the protocol for the one-pot synthesis of 9H-benzo[e]pyrrolo[2,1-b][1,3]oxazines is also presented.

N-Alkyl pyrroles are obtained in a single step from 4-hydroxyproline and aldehydes in just 15 min under microwave irradiation.
