No full textFirst Enantioselective Synthesis of Vinyl Oxiranes from Aldehydes and Ylides Generated from Allyl Halides and Chiral Sulfides
No full textAsymmetric allylidenation of aldehydes with
sulfur ylides is possible with proper substitution of the initial
sulfide, to avoid the [2,3] sigmatropic rearrangement of the
unsaturated ylides. One-pot reaction of (2R,5R)-dimethylthiolane with allyl halides, aldehydes, and sodium hydroxide
in tert-butyl alcohol affords vinyl oxiranes in good yields.
Enantiomeric excesses up to 90% and trans selectivities have
been achieved with methallyl-type halides
A Bibliography on the Social and Economic Phases of Dentistry and Other Health Services**This bibliography is the result of a cooperative effort on the part of Dr. L. E. Kurth, Mrs. Josephine Hunt, Librarian of the American Dental Association, and Dr. H. E. Phillips, and is sponsored by the Economics Committee of the American Dental Association of which Dr. E. H. Bruening is chairman. Other members of the Committee are Drs. John T. Hanks, R. H. Miller, H. W. Oppice and Leland R. Packwood. The Committee recognizing the need of such a bibliography had arranged that the work be done in the American Dental Association Library. When it was learned that Doctors Kurth and Phillips had already started such a bibliography, a joint effort in completing the work was agreed on. Much of this material is available from the American Dental Association Library Bureau.Such topics as would be included under the subject headings voluntary insurance, compulsory insurance, state dentistry, state medicine and socialized medicine are included in the bibliography.
