Synthesis of ethyl pyrrole-2-carboxylates: A regioselective cyclization of enaminones under knorr-type conditions

A regioselective formation of ethyl pyrrole-2-carboxylates 4 and 5 is effected by reductive condensation of enaminones 1a-f and ethyl 2-oximinoacetoacetate 2. The structures of the products have been delineated by spectroscopic methods.

Provided is a compound represented by formula (1) or a pharmacologically acceptable salt thereof. (In the formula, A is C6-10 arylene, etc.; R1a, R1b and R1c each independently is a hydrogen atom, a halogen atom, a C1-4 alkyl group, a C1-4 alkoxy group, etc.; R2 is an optionally substituted C6-10 aryl group, an optionally substituted 5- to 12-membered monocyclic or polycyclic heteroaryl group, an optionally substituted C7-16 aralkyl group, etc.; m is 0, etc.; n is an integer of 0 to 2.)

Linearly -π- extended porphyrins: Synthesis of novel tetrabenzoylporphyrins

The π-extended porphyrins 11a - c with a λmax = 644, 643 and 639 nm were synthesized by an acid catalysed reaction of the dipyrrolylmethane 10 with different aldehydes followed by oxidation with 2,3-dichloro-5,6-dicyano-1,4-quinone (DDQ). In a

The Synthesis and Transformation of Ethyl 2-(2-Acetyl-2-benzoyl-1-ethenyl)amino-3-dimethylaminopropenoate. A new Synthesis of 2,3,4-Trisubstituted Pyrroles

The synthesis of ethyl 2-(2-acetyl-2-benzoyl-1-ethenyl)amino-3-dimethylaminopropenoate (4) from benzoylacetone (1) via 3-dimethylaminomethylenebenzoylacetone (2) and ethyl N-(2-acetyl-2-benzoyl-1-ethenyl)glycinate (3) and its transformation into 4-benzoyl-2-ethoxycarbonyl-3-methylpyrrole (9) is described. Cyclization of 4 into 9 represents a new synthesis of polysubstituted pyrroles.

A Simple Synthesis of Pyrroles

A new, convenient procedure is described for the synthesis of pyrroles by cyclocondensation of 2-amino-1-alkenyl ketones with α-aminocarbonyl compounds.
