tert-Pentyl groups are recognized to be highly effective steric groups that can enhance enantioselectivity of salen titanium complexes when they are used in asymmetrical cyanation of aromatic aldehydes. High ee (92-97%) has been obtained with several aldehyde substrates. Compared to its tert-butyl analogue, the tert-pentyl group has been found to improve enantioselectivity and in some cases quite dramatically.
Novel (R)-oxynitrilase sources for the synthesis of (R)-cyanohydrins in diisopropyl ether

Apple, apricot, cherry and plum meal were prepared from the seeds or kernels of mature garden fruits. The preparations as well as almond meal were used as the source of (R)-oxynitrilase for the synthesis of aliphatic and aromatic cyanohydrins in diisoprop
