This present disclosure provides compositions comprising E-10-0H-NT metabolites of AT and NT, methods for their synthesis and methods for their use In one embodiment, the compound (-)-E-5-(y-bromo.rho.ropylidene)-10,11-d.iota.hydro-IO-hydroxy-5H-dibenzo[a,d]- cycloheptene. Is prepared by reducing E-5-(y-bromopropylidene)-10,11d.iota.hydro-IO-oxo-5H-d.iota.benzo[a,d] ?cycloheptene in the presence of a crural-specific oxazaborolidine catalyst In another embodiment, method for inhibiting uptake of norepinephrine comprising contacting a norepinephrine transporter with a composition comprising E-IO-OH-NT that is enriched in the (-) enantiomer Is described

L'invention concerne des compositions comprenant des métabolites E-10-OH-NT de AT et NT, des procédés pour leur synthèse et des procédés pour leur utilisation. Dans un mode de réalisation, le composé (-)-E-5-(y-bromopropylidène)-10,11-dihydro-IO-hydroxy-5H-dibenzo[a, d]-cycloheptène est préparé en réduisant le (-)-E-5-(y-bromopropylidène)-10,11-dihydro-IO-oxo-5H-dibenzo[a, d]-cycloheptène en présence d'un catalyseur d'oxazaborolidine spécifique crurale. Dans un autre mode de réalisation, le procédé pour inhiber l'absorption de norépinéphrine comprenant la mise en contact d'un transporteur de norépinéphrine avec une composition comprenant E-10-OH-NT qui est enrichie en énantiomère (-) est décrit.
