A bio-catalyzed N-formylation reaction of different amines has been developed using ethyl formate as a formylating agent. This protocol provides a facile and convenient strategy featuring mild reaction conditions, high efficacy, a broad substrate scope and recyclability of lipase. This method also works on a large scale in high yield.

The 2R*,11bS* and 2S*,11bS* diastereoisomers of the spiroquinolizine-2,5'-oxazolidin-2'-one> system were prepared by stereoselective methods.Evaluation of these compounds for antihypertensive activity by oral administration to the spontaneously hypertensive rat showed the 2S*,11bS* series was the more potent.Within that series it was found that small alkyl substituents at positions 3 and 4' enhanced antihypertensive activity and that methoxyl substitution at positions 9 and 10 was optical. (2S,3S,11bS)-Spiroquinolizine-2,5'-oxazolidin-2'-one> was one of the most efficacious compounds of this series, while its antipode, (+)-9e, was inactive.Selected compounds in this series were shown to be α-adrenoceptor antagonists.
