Several novelchiralbifunctional L‐thiazoline‐thioureaderivatives were easily synthesized from commercially available L‐cysteine in high yield. These catalysts were subsequently applied to the enantioselective Michael addition of acetylacetone to β‐nitrostyrenes. The products with S configuration were obtained in 98% enantiomeric excess (ee) when the L‐thiazoline‐thioureaderivatives were used. A
A photoredox-catalyzed multifluoromethyl radical addition/SO2 incorporation/polar cyclization cascade approach to multifluoromethylated γ-sultines has been developed. The reaction proceeds with broad functional-group tolerance and good yields. Key to the success of the protocol is use of oxidizable multifluoroalkanesulfinates as bifunctional reagents.

(EN) The present invention relates to the compositions, methods, and applications of a novel approach to selective inhibition of several cellular or molecular targets with a single small molecule. More specifically, the present invention relates to multi-functional small molecules wherein one functionality is capable of inhibiting histone deacetylases (HDAC) and the other functionality is capable of inhibiting a different cellular or molecular pathway involved in aberrant cell proliferation, differentiation or survival.(FR) L'invention concerne des compositions, des procédés, et des applications d'une approche nouvelle permettant d'effectuer une inhibition sélective de plusieurs cibles cellulaires ou moléculaires à l'aide d'une seule petite molécule. En particulier, l'invention concerne de petites molécules multifonctionnelles présentant une fonction d'inhibition d'histone désacétylases (HDAC) et une autre fonction permettant d'inhiber une voie cellulaire ou moléculaire différente impliquée dans une prolifération cellulaire aberrante, dans une différenciation cellulaire aberrante ou dans une survie cellulaire aberrante.
2-Ethoxy-2-propenyl Diethyl Phosphate. An Efficient Halo Acetone Equivalent for the Pd-Catalyzed Cross-coupling with Tin Enolates
In the presence of Pd(0) complexes, 2-ethoxy-2-propenyl diethyl phosphate was found to react with organotins to give the corresponding coupling products, showing to be a more efficient halo acetone equivalent compared with the corresponding acetate or carbonate. Reaction with tin enolates gave the 1,4-diketone in moderate to good yields.
