Biomimetic syntheses of lamellarin and lukianol-type alkaloids

The formation of 3,4-diarylpyrrole-2,5-dicarboxylic acids from arylpyruvic acids and 2-arylethylamines was used as a key step for the synthesis of several marine pyrrole alkaloids. The utility of this method is illustrated through the development of synth

ANTITUMORAL ANALOGS OF LAMELLARINS

New lamellarins are provided of the general formula III wherein X is selected from the group consisting of N, O and S; wherein R1, R2, R3, R4, R5, R6, R7, R8 and Rsub

Convergent total synthesis of lamellarin K

The azomethine ylide derived from dihydroisoquinolinium salt 24 undergoes an intramolecular [3 + 2] cycloaddition reaction to give pyrrole 25 which upon de-isopropylation affords the marine alkaloid lamellarin K 4.
