  • Process for the enantioselective preparation of phenylisosrine derivatives
    Patent number: 5463106
    Abstract: Process for the enantioselective preparation of phenylisoserine derivatives of general formula (I), in which R represents a phenyl or tert-butoxy radical, R.sub.1 represents a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms and R.sub.2 represents a hydrogen atom or a group protecting the alcohol function.
    Type: Grant
    Filed: March 9, 1994
    Date of Patent: October 31, 1995
    Assignee: Centre National de la Recherche Scientifique
    Inventors: Arlene G. Correa, Jean-Noel Denis, Andrew E. Greene

  • Process for preparing taxol
    Patent number: 4924011
    Abstract: Process for preparing taxol by the condensation of a (2R, 3S) acid of general formula (I) with a taxan derivative of general formula (II), followed by the removal of the groups R.sub.2 and R.sub.3 protecting the hydroxy groups.
    Type: Grant
    Filed: April 3, 1989
    Date of Patent: May 8, 1990
    Assignee: Centre National De La Recherche Scientifique
    Inventors: Jean-Noel Denis, Andrew E. Greene, Daniel Guenard, Francoise Gueritte-Voegelein
  • Manufacture of 2-(alkyl, alkenyl or alkynyl) 3-carbalkoxyalkyl ketones from alpha, beta-unsaturated ketones
    Patent number: 4143230
    Abstract: The copper enolate of 3-allylcyclopentanone is alkylated with an alkyne so as to form the 2-alkynyl, 3-allylcyclopentanone which is then subjected to ozonolysis and oxidative cleavage to form 2-alkynylcyclopentan-3-one-1-yl alkylcarboxlic acid. The acid can be esterified to form a 2-alkynyl-3-carbalkoxyalkyl ketone which, in turn, can be hydrogenated to convert the alkynyl moiety to alkenyl or alkyl moieties. The procedure is particularly useful in the synthesis of methyl dl-jasmonate, dehydrojasminate and dihydrojasmonate.
