Certain formyl peptides are powerful chemoattractants towards neutrophils. In this study, several formyl tripeptides were synthesized and used to investigate the effects of different amino acid residues in position 1 on their ability to stimulate neutrophil chemotaxis. Pig neutrophil chemotaxis towa

β¦ Synopsis
Our previous studies with several tricyclic halocyclopropanee indicate that in these systems "full-fledged" cyclopropyl cations are not reaction intermediates; rather, a partially opened species is implicated which begins to resemble a perpendicular ally1 cation.L Examination of molecular models demonstrates that

## Abstract The ^1^H magnetic resonance spectrum of the title compound has been completely analysed, using 60, 100 and 220 MHz spectrometers. The values of the chemical shifts and coupling constants obtained confirm the proposed structure and also provide information on the conformation. The molecu
