✦ Synopsis


Two penicillin analogues have been prepared which incorporate C=C bonds at C60 and C6B respectively, in place of the normal side-chain NHCO group. The concept of isosteric replacement of an amide function by a carbon-carbon double bond has recently been exemplified in the synthesis of active enkephalin analogues.
