  • Organophosphorus intermediates. VI. The acid-catalysed reaction of trialkyl orthoformates with phosphinic acid
    作者:MJ Gallagher、H Honegger
    DOI:10.1071/ch9800287
    日期:——

    Trialkyl orthoformates react with phosphinic acid to give the corresponding alkyl phosphinate and alkyl mono- or bis- (dialkoxymethyl)phosphinates; dialkyl phosphonites and phosphine, PH3, are also formed. The formation of P-alkylated products is acid- catalysed and is believed to proceed by alkylation of the trivalent tautomer of phosphinic acid (or its ester) by the dialkoxymethyl carbonium ion arising from the ortho ester in the presence of acid. A comparison with the corresponding reactions of phosphonic acid suggests that the trivalent tautomer of phosphinic acid [HP(OH)2] is formed much more readily than the trivalent form of phosphonic acid [P(OH)3] and this is accounted for by proposing that the equilibria RPH(O)OR′ +H+ ↔ RP+H(OH)OR' ↔ RP(OH)OR'+H+ (R = H, OH; R' = H, alkyl) lie further to the right for R = H than for R = OH because of inductive effects. 31P and 1H n.m.r. data are reported.

    Novel phosphinic acid-containing peptidyl compounds of formula I are found to be useful inhibitors of matrix metalloendoproteinase-mediated diseases including osteoarthritis, rheumatoid arthritis, septic arthritis, tumor invasion in certain cancers, periodontal disease, corneal ulceration, proteinuria, dystrophobic epidermolysis bullosa, and coronary thrombosis associated with atherosclerotic plaque rupture. These inhibitors may also be useful in preventing the pathological sequelae following a traumatic injury that could lead to permanent disability. These compounds may also have utility as a means for birth control by preventing ovulation or implantation. ##STR1##
