The B(C6F5)3-catalyzed hydrogenation is applied to aldoxime triisopropylsilyl ethers and hydrazones bearing an easily removable phthaloyl protective group. The C=N reduction of aldehyde-derived substrates (oxime ethers and hydrazones) is enabled by using 1,4-dioxane as the solvent known to participate as the Lewis-basic component in FLP-type heterolytic dihydrogen splitting. More basic ketone-derived hydrazones act as Lewis bases themselves in the FLP-type dihydrogen activation and are therefore successfully hydrogenated in nondonating toluene. The difference in reactivity between aldehyde- and ketone-derived substrates is also reflected in the required catalyst loading and dihydrogen pressure.

N-Alkylaminophthalimides were synthesized by condensation of N-aminophthalimide with aldehydes, and subsequent reduction of the intermediate with pyridine-borane in acetic acid. N-Phenylation and removal of the phthalimide group gave 1-alkyl-1-phenylhydrazines in high yield.
Regioselective Reduction of 2-(Arylideneamino)isoindole-1,3-diones - Synthesis of Alkaloid Analogues by N-Acylhydrazonium Ion Aromatic π-Cyclization

Hydroxylactams 6a-c and 7a-c were synthesized by successive regioselective reductions of arylideneaminophthalimides 3a-c, which were easily available from aminophthalimide 1 and benzaldehyde (2a) or thiophenecarboxaldehydes 2b and 2c. N-Acylhydrazonium io
