Trichloromethyl- and tribromomethyl-tributyltin give adducts with aldehydes. On acidolysis the corresponding trichloromethyl- and tribromomethylcarbinols are obtained in good yields. The stereochemistry of the addition reaction with hydratropic aldehyde was investigated and the substituent effects were determined by means of competitive experiments with substituted benzaldehydes. The inefficiency of

A series of 5-amino-6-cyclohexyl-4-hydroxy-hexanamide derivatives of Formula I have been synthesized.
As inhibitors of the production of β-amyloid protein from β-amyloid precursor protein, these compounds are expected to be effective in treating patients suffering from or susceptible to conditions or disorders linked to brain accumulation of β-amyloid protein; e.g., Alzheimer's Disease and Down's Syndrome.
