Total synthesis of lycoperdic acid and its C4-epimer
Morokuma,Irie, Raku,Oikawa, Masato
, p. 2067 - 2069 (2019)
Efficient stereodivergent syntheses of (+)-lycoperdic acid (LPA) and 4-epi-LPA have been achieved based on asymmetric hydrogenation (H2, Rh/(R,S)-MeBoPhoz) of racemic enamide as a key step.
Synthesis of both enantiomers of lycoperdic acid, an unusual mushroom-derived amino acid
Ishigami, Ken,Ishiuchi, Ryutaro,Katsuta, Ryo,Kunisawa, Mikiko,Nukada, Tomoo,Yajima, Arata
, p. 154 - 159 (2021)
An efficient synthesis of both enantiomers of lycoperdic acid, a 4-hydroxyglutamic acid derivative from edible mushroom Lycoperdon perlatum, was achieved from a chiral aminoalcohol. The key steps were a stereoselective introduction of a C3 unit into a bicyclic ketone and oxidative cleavage of a cyclic vicinal diol into a dicarboxylic acid. This report provides the first synthesis of (?)-lycoperdic acid.
3-Alkyl-1,2-cyclopentanediones by Negishi cross-coupling of a 3-bromo-1,2-cyclopentanedione silyl enol ether with alkylzinc reagents: An approach to 2-substituted carboxylic acid γ-lactones, homocitric and lycoperdic acids

Negishi cross-coupling of the silyl-protected 3-bromoenol of 1,2-cyclopentanedione with primary and secondary alkylzinc reagents using Pd-catalysts affords 3-alkyl substituted 1,2-cyclopentanediones in good yield. The method was applied to obtain 3-methyl
Diastereoselective synthesis of glutamate-appended oxolane rings: Synthesis of (S)-(+)-lycoperdic acid
Cohen, Jamie L.,Chamberlin, A. Richard
, p. 9240 - 9247 (2008/03/14)
(Chemical Equation Presented) The stereocontrolled synthesis of the glutamate-containing natural product (S)-(+)-lycoperdic acid is described. The key transformation in the synthetic route was an efficient diastereoselective annulation of an oxolane ring
Stereoselective syntheses of 4-hydroxy 4-substituted glutamic acids
Tamura, Osamu,Shiro, Tomoya,Ogasawara, Mizuho,Toyao, Atsushi,Ishibashi, Hiroyuki
, p. 4569 - 4577 (2007/10/03)
The 4-hydroxy 4-substituted glutamic acid moiety is a common substructure of biologically important natural products such as monatin [(2S,4S)-2], lycoperdic acid (3), and dysiherbaine (4). To develop methodology for syntheses of these natural products, cycloadditions of nitrone 5 with 2-substituted 2-propen-1-ols 6 and 2-substituted acrylates 8 were investigated. Reactions of nitrone 5 with alcohols 6 in the presence of MgBr2OEt2 gave cycloadducts 7 in a highly stereoselective manner, whereas noncatalyzed reactions of 5 with acrylates 8 afforded adducts 9. Using the former reaction, syntheses of monatin [(2S,4S)-2], monatin derivative 18, and lycoperdic acid (3) were accomplished. The C4-epimer of monatin [(2S,4R)-2)] was also synthesized by employing the latter cycloaddition.
Stereoselective synthesis of (S)-(+)-lycoperdic acid through an endo selective hydroxylation of the chiral bicyclic lactam enolate with MoOPH

, p. 9737 - 9740 (2007/10/03)
Efficient synthesis of (S)-(+)-lycoperdic acid has been achieved by use of the stereoselective hydroxylation of the enolate derived from the bicyclic lactam 3 with the molybdenum oxidizing reagent, MoOPH (MoO5·Py·HMPA, oxodiperoxymolybdenum(pyr
Stereocontrolled synthesis of (+)-lycoperdic acid based on a palladium catalyzed reaction using a serine-derived organozinc reagent
Masaki, Hidekazu,Mizozoe, Tomoko,Esumi, Tomoyuki,Iwabuchi, Yoshiharu,Hatakeyama, Susumi
, p. 4801 - 4804 (2007/10/03)
An efficient stereocontrolled synthesis of (+)-lycoperdic acid has been achieved based on palladium catalyzed cross-coupling reaction of (Z)-1-(tert- butyldimethylsiloxy)-3-iodo-6-(p-methoxybenzyl)oxy-2-hexene with the organozinc reagent, prepared from N-Boc-β-iodoalanine methyl ester.

Asymmetric synthesis of lycoperdic acid
Yoshifuji,Kaname
, p. 1617 - 1620 (2007/10/03)
Lycoperdic acid [(2S,5'S)-2-amino-3-(5'-carboxy-2'-oxo-5'- tetrahydrofuranyl)propanoic acid], isolated from the mushroom Lycoperdon perlatum, was synthesized from trans-4-hydroxy-L-proline by a six-step route involving samarium diiodide (SmI2)-mediated formation of the spiro-γ- lactone and ruthenium tetroxide (RuO4) oxidation of the L-proline ring system to the L-pyroglutamic acid moiety. Lycoperdic acid (1) was found to undergo hydrolysis of the γ-lactone ring in 1 N hydrochloric acid at 23°C, giving an equilibrated mixture of 1 and the corresponding hydroxy acid.
