Keenan, Thomas published the artcilePhase-Transfer-Catalyzed Alkylation of Hydantoins, HPLC of Formula: 111-83-1, the publication is ACS Organic & Inorganic Au (2022), 2(4), 312-317, database is CAplus.
A highly efficient, cost-effective and environmentally friendly protocol was reported for the synthesis of alkylated hydantoins I [R = allyl, Bn, CH2C≡CH, etc.; R1 = H, Me, Bn, etc.; R2 = Me, allyl, octyl, Bn, 4-MeOC6H4CH2; R3 = Me, Ph, Bn, etc.; RR1 = (CH2)4; R1R2 = (CH2)3] via C5-selective alkylation of hydantoins under phase-transfer catalysis. The reactions were scalable and only required a catalytic amount of tetrabutylammonium bromide (TBAB) to achieve high yields under mild reaction conditions. Moreover, the method was applicable to a wide range of electrophiles, including alkyl-, allyl-, propargyl- and benzyl halides, as well as acrylates and dibromoalkanes, but also to virtually any hydantoin precursor. The potential for an enantioselective adaptation using a chiral phase-transfer catalyst was also highlighted.
