Stereoselectivity in the cyclisation of photoinduced electron transfer (PET) generated cyclic (α -amino radicals: First general stereoselective entry to 1-azabicyclo (m:n:o) alkane systems
摘要:
Stereoselectivity in the intramolecular cyclisation of PET-generated cyclic alpha-amino radicals and its application to the synthesis of 1-azabicyclo (m:n:o) alkane systems is reported.
This disclosure concerns compounds which are useful as inhibitors of protein kinase C (PKC) and are thus useful for treating a variety of diseases and disorders that are mediated or sustained through the activity of PKC. This disclosure also relates to pharmaceutical compositions that include these compounds, methods of using these compounds in the treatment of various diseases and disorders, processes for preparing these compounds and intermediates useful in these processes.
Stereoselectivity in the photoinduced electron transfer (PET) promoted intramolecular cyclisations of 1-alkenyl-2-silyl-piperidines and -pyrrolidines: rapid construction of 1-azabicyclo[m.n.0]alkanes and stereoselective synthesis of (±)-isoretronecanol and (±)-epilupinine
PET promoted cyclisations of 1-alkenyl-2-silyl-pyrrolidines and -piperidines 9a-d to 1-aza-bicyclo[m.n.0]alkanes have been found to be stereoselective. The five-membered ring formation gives predominantly cis products while six-membered rings are trans. Application of such cyclisations to the synthesis of (+/-)-isoretronecanol 22a, (+/-)-epilupinine 29 and related alkaloids has been demonstrated.
