Total syntheses of pyocyanin, lavanducyanin, and marinocyanins A and B have been accomplished. The N-substituted phenazin-1-one skeleton, a common framework of these natural products, was constructed through the oxidative condensation of pyrogallol with N-substituted benzene-1,2-diamine under an oxygen atmosphere in a single step. Regioselective bromination with N-bromosuccinimide at the C-2 position of N-alkylated phenazin-1-ones afforded brominated natural products.

A given compound is synthesized simply, efficiently, and selectively. Specifically, provided are a method for producing (2,4,4-trimethyl-1-cyclohexene)carbaldehyde including at least a step for obtaining a 2,4,4-trimethyl-2-cyclohexenylidene methyl ether compound (2) by reacting the carbonyl groups of 2,4,4-trimethyl-2-cyclohexenone (1) and a step for obtaining (2,4,4-trimethyl-1-cyclohexene)carbaldehyde (3) by hydrolyzing (2), a method for producing (2,4,4-trimethyl-1-cyclohexene)methanol including at least a step for obtaining (2,4,4-trimethyl-1-cyclohexene)methanol (4) by reducing (3), and a method for producing a (2,4,4-trimethyl-1-cyclohexenyl)methyl ester compound including at least a step for obtaining a (2,4,4-trimethyl-1-cyclohexenyl)methyl ester compound (5) by esterifying (4).
Transition metals in organic synthesis, Part 98.1 Transition metal mediated total synthesis of the potent neuronal cell protecting alkaloid (±)-lavanduquinocin

, p. 330 - 342 (2013/09/24)
An efficient total synthesis of (±)-lavanduquinocin, a potent neuronal cell protecting alkaloid from Streptomyces viridochromogenes, is reported. Key-steps are an iron-mediated one-pot construction of the carbazole framework and a nickel-mediated coupling reaction. ARKAT-USA, Inc.
