A new class of chiral secondary amine organocatalyst was rationally designed as an efficient catalyst to catalyze the elusive Michael addition of aldehydes to vinyl sulfones. High yield and excellent enantioselectivities could be obtained at room temperature without having to resort to high catalyst loading, anhydrous solvents, and low temperatures.(More)
A new class of structurally rigid tricyclic amphibian chiral catalyst was rationally designed based on the hexahydropyrrolo[2,3-b]indole skeleton as a new type of chemzyme. This new type of chemzyme possesses a structurally rigid tricyclic skeleton and a chiral pocket which provides a well-organized chiral environment for asymmetric induction, as well as a(More)
OBJECTIVE To develop a special controlled-releasing long effect fertilizer (SCRLEF) for growing higher plant in controlled ecological life support system (CELSS). METHOD First, a plan was designed. According to requirements, some original fertilizers were chosen and compounded in proper proportions, and a granule product was obtained and encapsulated in(More)
The acid free asymmetric intermolecular α-alkylation of aldehydes with alcohols has been discovered using trifluoroethanol as solvent. This unprecedented system affords the enantioenriched functionalized primary alcohols (after NaBH(4) reduction) in high yields and good to excellent enantioselectivities with wide substrate scope in the absence of any acid(More)
