PROCESS FOR THE PREPARATION OF 4-PHOSPHINYL-3-KETO-CARBOXYLATE AND 4-PHOSPHONYL-3-KETO-CARBOXYLATE INTERMEDIATES USEFUL IN THE PREPARATION OF PHOSPHORUS CONTAINING HMG-COA REDUCTASE INHIBITORS

A process for the preparation of compounds of formula STR1 or salt thereof where R1 is --X--Z and X is --C C--, R2 and R2 ' are independently hydrogen, alkyl or trialkylsilyl; R3 is hydrogen or alkyl; and Z is a hydrophobic anchor; which includes reacting

PHARMACEUTICALS, PHOSPHORUS-CONTAINING 2-ISOXAZOLINES AND ISOXAZOLES CONTAINED THEREIN

Pharmaceuticals containing or composed of at least one compound of the formula I and/or one of its physiologically tolerated salts where appropriate, where the compounds of the formula I can, where appropriate, be in the form of pure stereoisomers or mixtures thereof; formula I is: STR1 in which R. sup.1 =organic radical or halogen, A=C,C single or C,C double bond,n=0, 1 or 2, and STR2 R 2 and R 3 =H or optionally substituted aliphatic radical. The pharmaceuticals are suitable for the prophylaxis and/or treatment of diseases of the immune system, especially of tumors, infections and/or autoimmune diseases of the human or animal body and for use as adjuvants for vaccines.Some of the compounds of the formula I are new; the compounds can be prepared by special processes.

Infrared Spectra of O-Atom-PH3 Reaction Products Trapped in Solid Argon

Argon/phosphine samples have been reacted with O atoms from a discharge, and the products trapped in solid argon for infrared spectroscopic analysis.Studies with isotopic precursors, stepwise photolysis, and sample annealing have made possible spectroscopic identification of PO, HPO, PO2, PO3, HOPO, P2O5, H2PO, and HPOH, the last five for the first time.The PO3 species appears to have D3h symmetry from the isotopic out-of-plane bending mode absorption.Molecular P2O5 is fromed on diffusion and reaction of PO2 and PO3.The major phosphine-oxygen atom reaction product H2PO photoisomerizes to HPOH.
