- Boronate Ester Bullvalenes
-
Boronate ester bullvalenes are now accessible in two to four operationally simple steps. This unlocks late-stage diversification through Suzuki cross-coupling reactions to give mono-, di-, and trisubstituted bullvalenes. Moreover, a linchpin strategy enab

- Regioselective synthesis of multisubstituted benzenes by palladium-catalyzed intermolecular reaction of β-iodo-β-silylstyrenes with alkynes
-
The Pd-catalyzed reaction between β-iodo-β-silylstyrenes and terminal alkynes in i-Pr2NEt gave 1,2,3,5-tetrasubstituted benzenes with complete regioselection. The use of certain silylacetylenes as alkynes enabled efficient synthesis of 1,3,5-trissilyl-2-arylbenzenes, which could be transformed into other multisubstituted benzenes by displacement of the silyl groups.

- Cobalt(I)-mediated preparation of polyborylated cyclohexadienes: Scope, limitations, and mechanistic insight
-
A series of 1,3- and 1,4-di-boryl-1,3-cyclohexadiencs have been prepared by intermolecular CoCp-mediated [2+2+2] cocyclizations of alkynylboronic pinacolate esters with alkenes, followed by oxidative demetallation with iron(III) chloride. The effect of su

-
(Chemical Equation Presented) Regio- and stereoselective enyne cross metathesis reactions between borylated alkynes and terminal alkenes were realized to provide a variety of functionalized vinyl boronates. High chemical yield and regioselectivity was ach
