In 2019,Tetrahedron Letters included an article by Arai, Shigeru; Kawata, Yuna; Amako, Yuka; Nishida, Atsushi. Recommanded Product: 609-08-5. The article was titled 《Nickel-catalyzed [2 + 2] cycloaddition reaction using bisallenes》. The information in the text is summarized as follows:
A nickel-catalyzed [2 + 2] cycloaddition of bisallenes was described for the synthesis of bicyclic compounds I [R1 = H, Me; R2 = H, Ph; X = NTs, C(CO2Et)2, C(CO2Me)(CN); Y = CH2, C(CH2)5, CHPh] and tricyclic compounds II [R3 = Me, i-Pr]. Simple bisallenes were employed for the formation of “”head to head”” cycloadducts in the presence of Ni(0) with xantphos. The dienyl moiety in a product was applicable for various [4 + 2] cycloaddition reactions. Allene-allenamides under Ni-xantphos system gave the tricyclic compounds II through sequential [2 + 2]-[4 + 2] cycloaddition reaction in highly stereoselective manner. In addition to this study using Diethyl 2-methylmalonate, there are many other studies that have used Diethyl 2-methylmalonate(cas: 609-08-5Recommanded Product: 609-08-5) was used in this study.
Diethyl 2-methylmalonate(cas: 609-08-5) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.Recommanded Product: 609-08-5
