Chandrashaker, Vanampally,Taniguchi, Masahiko,Ptaszek, Marcin,Lindsey, Jonathan S.
experimental part, p. 6957 - 6967 (2012/09/07)
A proposed chemical model for the prebiogenesis of tetrapyrrole macrocycles relies on the condensation of a 3-alkyl-substituted 2,4-diketone and an α-aminoketone to form a pyrrole equipped for subsequent self-condensation leading to porphyrinogens. The co
CONCERNING THE MECHANISM OF FORMATION OF BILIVERDINS FROM b-BILENES
Awruch, Josefina
, p. 1171 - 1180 (2007/10/02)
The oxidation of 1,19-di-t-butoxycarbonyl-b-bilenes with bromine affords not only a major biliverdin, but also minor biliverdins.Elucidation of their structure revealed that cleavage of the b-bilene chain takes place during the oxidation, followed by dime
ELECTROPHILIC HETEROAROMATIC SUBSTITUTIONS. VI. THE REACTION OF SOME 3,4,5-TRI- AND 1,3,4,5-TETRASUBSTITUTED 2-METHYLPYRROLES WITH MANNICH REAGENTS
Curulli, Antonella,Giardi, Maria Teresa,Sleiter, Giancarlo
, p. 115 - 122 (2007/10/02)
The reaction of a series of 3,4,5-tri- (1) and 1,3,4,5-tetrasubstituted (2) (2)-methylpyrroles with Mannich reagents formed in situ from a secondary aliphatic amine and formaldehyde has been investigated in aqueous acetic acid, methanol, and dioxan.No rea
