Stereoselective Synthesis of P-Chirogenic Dibenzophosphole–Boranes via Aryne Intermediates
摘要:
A new aryne-mediated tandem cross-coupling/P-cyclization sequence starting from tertiary phosphine-boranes and 1,2-dibromobenzenes is reported. P-chirogenic dibenzophospholes become accessible in a regio-, chemo-, and diastereoselectiye way.
