A convenient Fe-catalyzed decarbonylative alkylation-azidation cascade reaction of styrene derivatives with aliphatic aldehydes and TMSN3 to provide aliphatic azides is developed. With DTBP as an oxidant and radical initiator, this reaction smoothly converts aliphatic aldehydes into 1°, 2° and 3° alkyl radicals and subsequently allows for the cascade construction of C(sp3)-C(sp3) and C(sp3)-N bonds via radical insertion and nucleophilic azidation.

A series of 3-(2-aminocarbonyl-4-phenoxymethylphenyl)propanoic acid analogs were synthesized and evaluated for their EP3 antagonist activity in the presence of additive serum albumin. Several compounds were biologically evaluated for their in vivo efficacy with respect to the PGE2-induced uterine contraction in pregnant rats as well as their pharmacokinetics. The discovery process of these potent and selective EP3 antagonists and their structure activity relationship are also presented.
N-Tert-butyldimethylsilyl imines as intermediates for the synthesis of amines and ketones

Grignard reagents add to benzonitrile at low temperature catalyzed by CuBr and TBSCl affording N-TBS ketimines, which were investigated as intermediaries for the synthesis of primary amines and ketones. N- silylimines were easily obtained by an organolithium addition to benzonitrile followed by a reaction with TBSCl in CH2Cl2. In situ reduction of these imines by BH3 and 1,3,2-oxazaborolidines 1 or 2 as chiral templates afforded the corresponding amines with modest to good enantiomeric excess.
