Regio- and diastereoselective synthesis of multi-substituted silacyclopentanes by catalytic cyclosilylborylation of styryl(vinyl)silanes

Key Points

• The aim is to develop a catalytic method for the regio- and diastereoselective synthesis of multi-substituted silacyclopentanes using styryl(vinyl)silanes and silylboronates.
• Utilized NaO t Bu as a catalyst for the reaction.
• Performed cyclosilylborylation of styryl(vinyl)silanes with silylboronates.
• Focused on achieving both regio- and diastereoselectivity in the synthesis.
• Successfully synthesized 2-silyl-5-boryl-1-silacyclopentanes.
• The synthesized compounds can be further functionalized.
