Stereoselective synthesis of (6R)- and (6S)-diosphenol and Ψ-diosphenol
Schneider, David F,Viljoen, Murray S
, p. 5307 - 5315 (2007/10/03)
Methods are discussed for the stereoselective synthesis of the (R)-and (S)-enantiomers of the diosphenols (5)-(8) by utilizing the commercially available stereoisomers (9), (12), (23) and (25) of carvone and limonene, respectively, as chiral starting materials.

, p. 1285 - 1292 (2007/10/03)
Syntheses of diosphenol (3), ψ-diosphenol (4), 6-hydroxydiosphenol (5) and 6-hydroxy-ψ-diosphenol (6), which are constituents of the essential oil from Barosma betulina Bartl. (mountain buchu), are discussed.
Synthesis of annulated 4-alkylidenebutenolides from natural occurring diosphenols
Schneider, David F.,Viljoen, Murray S.
, p. 3349 - 3360 (2007/10/03)
Diosphenol (3) and Ψ-diosphenol (4), two constituents of the essential oil from the buchu plant, Borosma betulina (Bartl.), were utilized for the synthesis of the anulated 4-ylidenebutenolides (5) and (6).

Wahidullah, Solimabi,Paknikar, S. K.
, p. 880 - 881 (2007/10/02)
A simple and straightforward synthesis of the title compound (1) is described starting from menthone (2).The synthetic 2,3-dimethoxy-p-cymene (1) is not identical with the natural product reported by Zutshi and Bokadia .
Reaction of Singlet Oxygen with Enamino Carbonyl Systems. A General Method for the Synthesis of α-Keto Derivatives of Lactones, Esters, Amides, Lactams, and Ketones
Wasserman, Harry H.,Ives, Jeffrey L.
, p. 3573 - 3580 (2007/10/02)
A general method for the introduction of a ketone α to the carbonyl group of a ketone, lactone. ester, substituted amide, or lactam has been developed involving the formation and dye-sensitized photooxygenation of enamino carbonyl intermediates.
REGIOSELECTIVE MONOALKYLATION OF 3-METHYL-1,2-CYCLOHEXANEDIONE
Utaka, Masanori,Hojo, Makoto,Takeda, Akira
, p. 445 - 448 (2007/10/02)
Monoalkylation of 3-methyl-1,2-cyclohexanedione was achieved regioselectively to give 6-alkyl-3-methyl-1,2-cyclohexanedione as a major product without the formation of O-alkylated or polyalkylated products.
