Kreiser, Wolfgang,Wiggermann, Annette,Krief, Alain,Swinnen, Dominique
, p. 7119 - 7122 (1996)
Enedione 1 and related rac- and optically active enones 2 bearing a hydroxyl- 2a or a protected- 2b-c or an activated - 2d 4-hydroxyl group at C-4 have been efficiently synthesized from cheap and readily available starting materials.

, p. 4285 - 4288 (2017)
The stereoselective synthesis of compounds 5 and 6, potential hydroxylated metabolites of the agricultural fungicide cis-metconazole, is reported. In a key step of the initially surveyed synthetic route, hydrodechlorination of 12 was competitive with hydr
Selective Derivatization of N-Terminal Cysteines Using Cyclopentenediones

The outcome of the Michael-type reaction between thiols and 2,2-disubstituted cyclopentenediones varies depending on the thiol. Stable compounds with two fused rings were formed upon reaction with 1,2-aminothiols (such as N-terminal cysteines in peptides). Other thiols gave reversibly Michael-type adducts that were in equilibrium with the starting materials. This differential reactivity allows differently placed cysteines to be distinguished and has been exploited to prepare bioconjugates incorporating two or three different moieties.
A short, protecting group-free total synthesis of bruceollines D, E, and J

A short, protecting group-free total synthesis of bruceollines D, E, and J has been achieved. The enantioselective reduction of bruceolline E with β-chlorodiisopinocampheylborane delivers both the natural and unnatural enantiomers of bruceolline J in excellent yields and enantioselectivities. Reduction with baker's yeast and sucrose was shown to provide the unnatural enantiomer of bruceolline J in 98% ee.

Regio- and Stereoselective Syntheses of 7-Oxabicyclo[2.2.1]heptanes via a Gold(I)-Catalyzed Cycloisomerization of Alkynediols: Asymmetric Total Synthesis of Farnesiferol C
Gu, Yue-Qing,Zhang, Peng-Peng,Fu, Jun-Kai,Liu, Song,Lan, Yu,Gong, Jian-Xian,Yang, Zhen
supporting information, p. 1392 - 1397 (2016/05/19)
A highly regio- and stereoselective method to construct a broad range of 7-oxabicyclo[2.2.1]heptanes, which proceeds through a sequential reaction involving gold(I)-catalyzed cycloisomerization of alkynediols and sequential semi-pinacol-type 1,2-alkyl migration, was developed. The developed chemistry was applied to the asymmetric total synthesis of the natural product farnesiferol C.
