Copper-Catalyzed Aerobic Cyclization of β,γ-Unsaturated Hydrazones with Concomitant CC Bond Cleavage

, p. 7981 - 7985 (2020/11/02)
A Cu-catalyzed aerobic oxidative cyclization of β,γ-unsaturated hydrazones for the preparation of pyrazole derivatives has been developed. The hydrazonyl radical promoted the cyclization, along with a concomitant CC bond cleavage of β,γ-unsaturated hydrazones. This process has been verified via several control experiments, including a radical-trapping study, an 18O-labeling method, and the identification of the possible byproducts. The advantages of this reaction include operational simplicity, a broad reaction scope, and a mild selective reaction process.
A new organic transformation by introducing crotyl/allyltrifluoroborates in cross-coupling reaction with aroyl chlorides

Microwave irradiated PdCl2(dtbpf) catalyzed direct cross-coupling reaction of aroyl chlorides with potassium crotyl/ allyltrifluoroborates has been developed. Regioselectivity of the cross-coupling product is varied from crotyltrifluoroborate to allyltrifluoroborate.

A new and efficient method for the preparation of β,γ-unsaturated ketones has been achieved by the simple reaction of an acyl cyanide with ailyl, crotyl and prenyl bromides and ytterbium metal in absolute tetrahydrofuran.
Indium-mediated allylation of acyl cyanides in aqueous media: A convenient synthesis of β,γ-unsaturated ketones
Yoo, Byung Woo,Choi, Kwang Hyun,Lee, Sung Jae,Nam, Ghil Soo,Chang, Kwan Young,Kim, Sung Hoon,Kim, Joong Hyup
, p. 839 - 846 (2007/10/03)
The indium-mediated allylation reaction of acyl cyanides with allyl halides in aqueous media afforded a variety of β,γ-unsaturated ketones in moderate to good yields under mild and neutral conditions.
Diversity in the Lewis Acid-induced Reaction of Aldehydes with γ-Substituted Allylstannanes Depending upon the Substituent
Fujiwara, Jun,Watanabe, Masami,Sato, Tadashi
, p. 349 - 352 (2007/10/02)
Lewis acid-induced reaction of γ-substituted allylstannanes with aldehydes proceeded at the α-, β- or γ-position, depending upon the nature of the substituents.
Diversity in the reaction modes of anionic and cationic stannyl reagents: γ-chloro allylstannanes as a vinyl carbene equivalent, and its application for (+/-)-bakuchiol synthesis
Fujiwara, Jun,Sato, Tadashi
, p. 63 - 70 (2007/10/02)
Diversity in the reaction modes of anionic stannyl reagents is demonstrated by synthon representation.A new cationic stannyl reagent, γ-chloro allylstannane, has been developed as a vinyl carbene equivalent, and its utility is demonstrated by (+)-bakuchio
