Synthesis of trans-2-(1-aryl-1-methylethyl)cyclohexylamines.
As a first example of opening a secondary aziridine with a tertiary carbanion, the title amines (3a-c, aryl = phenyl, 4-tert-butylphenyl,2-naphthyl) were synthesized by opening N-(diphenylphosphinoyl)-7-azabicyclo[4.1.0]heptane, aziridine 1, with the corresponding alpha-potassium isopropylarenes, followed by a hydrolysis of the resulting phosphinamides 2a-c.

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
