A new pyrrolidinyl-isosteviol bifunctional organocatalyst was synthesized, which was applied to catalyze the asymmetric Michaeladdition between cyclohexanone and nitroolefins. With 10 mol % of the organocatalyst, the reaction proceeded in water in high yields (up to 99%) with excellent diastereoselectivities (anti/syn up to 98:2) and good enantioselectivities (up to 90% ee). The design of the proline-isosteviol
of hybrid catalysts incorporating chloramphenicol base with another chiral scaffold using a squaramide linker have been developed and successfully applied in Michael addition of 2,3-dihydrobenzofuran-2-carboxylates to nitroolefins. The controlling experiments suggested that the hybrid catalysts were more reactive than non-hybridized bifunctional catalysts and the matching of chiralities between two
The present invention relates to certain novel dithiocarbamate esters, methods for their synthesis and their use as bactericidal and fungicidal agents.
