A novel three-component reaction between isocyanides, isothiocyanates, and oxiranes has been developed for the synthesis of substituted oxathianes I (R1 = t-Bu, Cy, 2,6-Me2C6H3; R2 = i-Pr, Ph, 4-BrC6H4, etc.; R3 = Me, n-Bu, Me2CHOCH2, etc.; R4 = H, Me, Ph, 4-MeC6H4; R5 = H, Me, CH3OCO; R6 = H, Me) in acceptable to good yields. The product of the reaction could be modulated by using either Bu3P or tetrabutylphosphonium acetate (TBPAc) as an organocatalyst. This work offers an opportunity for the further implementation of isocyanides in library design. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8SDS of cas: 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. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.SDS of cas: 2253-73-8
