- Evaluation of Phosphinic Acid Derivatives as Reagents For Amine Protection in Peptide Synthesis
-
The results of a kinetic study of the acid-catalysed methanolysis of a series of N-(2-phenyl-ethyl)phosphinamides incorporating selected substituents on phosphorus have been evaluated in order to define the optimum reagent and conditions for amine protection of α-amino acids during peptide synthesis.

- GAS-PHASE PYROLYSIS OF TERVALENT PHOSPHORUS-OXY AND -THIA HETEROCYCLES: A NEW APPROACH TO SHORT-LIVED PENTAVALENT PHOSPHORUS COMPOUNDS HAVING CO-ORDINATION NUMBER 3
-
Generation of short-lived metaphosphonates by thermal fragmentation of cyclic phosphonites and their thia-analogues in the gas phase is described, including an elaboration of the method whereby a monomeric phosphonobenzene is detected unambiguously for the first time by an intra-molecular trapping reaction which also illustrates the considerable potential of such species in the synthesis of phosphorus heterocycles.

- Synthesis of Substituted Dibenzophospholes. Part 1.
-
Approaches to the synthesis of 4,6-diaryl-5-hydroxydibenzophosphole 5-oxides are described. 3,5,7-Trihydroxydibenzophosphole 5-oxide and several of its O-substituted derivarives were made either from 5-hydroxydibenzophosphole 5-oxide (convenient preparation described) by dinitration, reduction and tetrazotization or from 2,2'-dibromo-4,4'-dimethoxybiphenyl via lithiation and reaction with dichloromorpholinophosphine with subsequent oxidation. 3,5,7-Trihydroxydibenzophosphole 5-oxide could be selectively blocked in the 2,8-positions by methyl groups generated via a Mannich reaction.The bis-2-iodobenzyl ethers of 3,7-dihydroxy-5-methoxydibenzophosphole 5-oxide and of its 2,8-dimethyl derivative were cyclized by photolysis to form 4,6-diaryl derivatives in poor yield.
