Three in one: A highly efficient and mild PdII‐catalyzed carboesterification of alkenes with carboxylic alkyne derivatives proceeds through a domino‐type alkyne–alkene coupling/CO‐bond formation (see scheme). The stereoselectivity is controlled by the choice of substrates and temperature. The reaction provides a convenient method for the construction of naturally occurring biologically active compounds

1-Boraadamantane derivatives containing omega-functionalized substituents in the position 2 have been synthesized by hydroboration-isomerization of 7-(omega-X-alkyl)-3-borabicyclo[3.3.1]non-6-enes. The application of the method permitted the previously unreported preparation of intra-complexes of the 1-boraadamantane series (X, XI, XIII).
