title: Rapid leucine-enkephalin synthesis.
abstract: Leucine-enkephalin, a naturally occurring pentapeptide with morphine-like activity, has been synthesized by a fragment condensation liquid phase method using 1,3,4-trimethyl-delta 3-phospholene-1,1-dichloride as a coupling agent. The advantages of this method are discussed.
