Application
The purpose of (2S,3R)-3,4-Dihydro-3-isopropyl-2-phenyl-2H-pyrimido[2,1-b]benzothiazole is to serve as an efficient catalyst in various chemical reactions. It facilitates isothiourea-mediated intermolecular Michael addition-lactonisation and enables the asymmetric Michael-lactonisation of CF3-enones. It is instrumental in the α-functionalisation of 3-alkenoic acids and plays a crucial role in the isothiourea-catalyzed α-amination of carboxylic acids. Additionally, this compound catalyzes the O-to-C carboxyl transfer of furanyl carbonates and assists in the kinetic resolution of secondary alcohols. It also supports the α-amination of carboxylic acids when used with N-aryl-N-aroyldiazene, underscoring its versatility as a catalyst in organic synthesis.
