## Abstract A new synthesis of oxytocin is described. N‐CBO‐L‐glutaminyl‐L‐asparaginyl‐S‐benzyl‐L‐cysteinyl‐azide is reacted with L‐prolyl‐L‐leucyl‐glycinamide to give N‐CBO‐L‐ glutaminyl‐L‐asparaginyl‐S‐benzyl‐L‐cysteinyl‐L‐prolyl‐L‐leucyl‐glycinamide. After removal of the CBO group by HBr in acet

## Abstract N‐CBO‐L‐Glutaminyl‐L‐asparaginyl‐S‐benzyl‐L‐cysteinyl‐azide has been condensed with L‐prolyl‐ϵ‐N‐tosyl‐L‐lysyl‐glycinamide, giving N‐CBO‐L‐glutaminyl L‐asparaginyl‐S‐benzyl‐L‐cysteinyl‐L‐prolylϵ‐N‐tosyl‐L‐lysyl‐glycinamide, which after spliting of the CBO‐protecting group has been conde
Poly(ally1benzene)s were synthetised by Ziegler-Natta catalysts: [VCl, + Al [CH,CH(CH, ) , 1, ] and [TiC14 + Al [CH2CH(CH,)2I3]. Two different polymers were obtained. Examination of their microstructures by IR and 'H 13C NMR spectroscopy suggests that one of the polymerization mechanisms proceeds vi
