Pictet reversibility

Isotope-labeling experiments and the secondary formation of regioisomers show that the Pictet-Spengler condensation may be reversible under more vigorous conditions. ... [Pg.737]

On the basis of a rapid and reversible spiroindolenine mechanism, a pathway for the Pictet-Spengler reaction was proposed recently, which is consistent with all these stereochemical fmdings. ... [Pg.738]

It is interesting to note that, using complementary DNA (cDNA) (Chapter 14), that is, DNA obtained by synthesis from a messenger RNA (mRNA) template in a reaction catalyzed by reverse transcriptase enzyme, the norcoclaurine synthase enzyme has been characterized, and the pathway from the precursors has been shown to most likely involve imine formation and then cyclization in a process resembling the Pictet-Spengler reaction. ... [Pg.1294]
