1,1′-spirobiindaneaminalizationchiral Brønsted aciddisulfonic aciddisulfonimideThe catalytic asymmetric direct Mannich-type reaction between aldimines and 1,3-dicarbonyl compounds is one of the most important carbon-carbon bond-forming reactions in organic chemistry. The resulting Mannich adducts can ...
The modifier “about” used in connection with a quantity is inclusive of the stated value and has the meaning dictated by the context (for example, includes the degree of error associated with measurement of the particular quantity). Unless otherwise specified, the term “cycloaliphatic functionalit...
