This Thesis details the development of a series of rhodium catalysed asymmetric additions to activated aldimines to give enantioenriched protected secondary amines. A particular focus has been the choice of activating group to allow deprotection of the protected amines under mild conditions, which would tolerate a wide substrate scope.Initially methyl addition to give enantioenriched arylethanamines was studied, using diphenylphosphinoyl imines, dimethylzinc as the methyl source with rhodium catalysis in the presence of a bidentate phosphine ligand. Reduction of the starting material was identified as side reaction with a MeerweinVerleyPonndorf type mechanism for the reduction being proposed.

This exists? Here? No way.” So I literally kept the trunk of my car packed with a tent and a cooler, and I would go over to a place called McClellan’s and go fishing at least once a month. That was in 2000, and then in 2009 I bought a house over there, and then in 2015 I bought this building that the brewery’s in. It was totally blown out.
