Epi-b-santalene (I; R = H), readily accessible in both enantiomeric forms, was regio- and stereoselectively converted into (R)-(-)- or (S)-(+)-(Z)-epi-b-santalol (I; R = OH) by consecutive metalation, borylation and oxidn. [on SciFinder (R)] ...
During the course of mass spectral studies on the stability of bimetallic systems, an exceptionally abundant and stable Na6Pb cluster was discovered. For given exptl. conditions, an intense mol. beam consisting exclusively of the particle Na6Pb is generate ...
The nucleation, growth, and orientation of lead zirconate titanate thin films prepared from organometallic precursor solutions by spin coating on (111) oriented platinum substrates and crystallized by rapid thermal annealing was investigated. The effects o ...
At low temperature 1-alkoxy-1,3-dienes add to sulfur dioxide activated by a Lewis or Bronstedt acid and generate zwitterionic intermediates that can be quenched by enoxysilanes. The resulting beta,gamma -unsaturated silyl sulfinates can be desilylated and ...
Zinc iodide‐catalyzed cycloaddition of furan to 1‐cyanovinyl (1′S)‐camphanate or 1‐cyanovinyl (1′R)‐camphanate led to optically pure (1R,2S,4R)‐2‐exo‐cyano‐7‐oxabicyclo[2.2.1]‐hept‐5‐en‐2‐yl (1S')‐camphanate and (1S,2R,4S)‐2‐exo‐cyano‐7‐oxabicyclo[2.2.1]he ...
