✦ Synopsis

We have recently investigated the addition of racemic and chiral, mixed lithium diorganocuprates, LiRR'Cu, to methyl trans-cinnamate' and methyl trans-3-(2-furanyl)acrylate. 2 With R being an alkyl or phenyl group and R' being a chiral 2-(l-dimethylaminoethyl)phenyl group a small optical rotation can be observed in the conjugate addition product.

In the cyclisation of the diazo-compound (7) to give the diastereomerit pair of lH-2,3\_benzodiazepines (8) and ( 9), alkoxy groups, when present as the medium sized group M, show the opposite effect in promoting face selectivity to that of alkyl groups and the alkoxide ion. Thus when M=OMe the ( 8
