The [3+2] cycloaddition of azaoxyallyl cations, in situ generated from α-halohydroxamates R1R2CXC(O)NHOCH2Ph [R1 = H, Me, Cl; R2 = Cl, Me, Ph; R1R2 = (CH2)5; X = Br, Cl], with isothiocyanates R2NCS (R2 = Me, i-Pr, cyclohexyl, Ph, PhCH2, etc.) proceeded smoothly in the presence of Na2CO3 and furnished the corresponding (Z)-3-(benzyloxy)-2-imino-thiazolidin-4-ones I in 25-99% yields. The structure of iminothiazolidinone I [R1 = R2 = Me; R3 = 1,5-Me2-2-oxoindolin-3-yl] was confirmed by X-ray single-crystal structure anal. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Product Details of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Product Details of 2253-73-8
