Peran utamanya adalah menginduksi selektivitas enantiomer pada reaksi adisi dan sikloadisi tanpa memerlukan kompleks logam transisi.\u003c\/p\u003e\u003cp\u003eKatalis imidazolidinon MacMillan dipakai peneliti sintesis asimetris untuk reaksi Diels-Alder, Michael, dan alkilasi konjugasi pada aldehida serta keton α,β-tak jenuh, menghasilkan produk dengan selektivitas enantiomer tinggi. Bentuk garam hidroklorida umum digunakan karena lebih stabil dan mudah ditangani sebelum dinetralkan menjadi basa bebas aktif di dalam campuran reaksi. Kelompok riset katalisis organik dan metodologi sintesis sering menjadikannya alternatif katalis berbasis logam.\u003c\/p\u003e\u003cp\u003eContoh produk dalam koleksi ini: \u003ca href=\"\/en\/products\/tci2510t299154500\"\u003eTCI T2991 278173-23-2 (S)-(-)-5-Benzyl-2,2,3-trimethyl-4-imidazolidinone Hydrochloride\u003c\/a\u003e, \u003ca href=\"\/en\/products\/tci2510b413710311\"\u003eTCI B4137 390766-89-9 (2R,5R)-(+)-2-tert-Butyl-3-methyl-5-benzyl-4-imidazolidinone\u003c\/a\u003e, \u003ca href=\"\/en\/products\/tci2510t299054498\"\u003eTCI T2990 323196-43-6 (R)-(+)-5-Benzyl-2,2,3-trimethyl-4-imidazolidinone Hydrochloride\u003c\/a\u003e, \u003ca href=\"\/en\/products\/tci2510b413810313\"\u003eTCI B4138 346440-54-8 (2S,5S)-(-)-2-tert-Butyl-3-methyl-5-benzyl-4-imidazolidinone\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003ePemilihan bergantung pada konfigurasi stereokimia (R) atau (S) yang sesuai dengan produk target, serta bentuk garam hidroklorida versus basa bebas tert-butil yang memengaruhi penanganan dan kelarutan pada pelarut reaksi.
