Abstract
![]()
Benzofused seven-membered heterocycles
such as 1,4-benzo[e]diazepines (1,4-BZDs) and 1,4-benzo[e]oxazepines (1,4-BZOs) were efficiently synthesized by
Rh-catalyzed
hydrofunctionalization of internal alkynes and allenes in good to
excellent yields. The asymmetric hydroamination of (aminomethyl)anilines
gave rise to 3-vinyl-1,4-BZDs with excellent enantioselectivities.
Orthogonal N-deprotection of 1,4-BZDs allowed an
easy entry to an advanced pyrrolobenzodiazepine metabolite of the
V2-receptor antagonist Lixivaptan.

Abstract
A rhodium/silver synergistic catalysis has been established, enabling cycloisomerization/cross coupling of keto-vinylidenecyclopropanes (VDCPs) with terminal alkynes toward the regio- and enantioselective formation of diversified tetrahydropyridin-3-ol tethered 1,4-enynes in good yields and high ee values. In this synergistic catalysis, Rh(I) and Ag(I) catalysts selectively activate keto-VDCP substrates and terminal alkynes to generate the π-allyl Rh(III) complex of oxa-rhodacyclic intermediate and Ag alkynyl intermediate, respectively. The rapid transmetalation of alkynyl groups from Ag to Rh is proposed to play a key role in realizing the regioselective cleavage of the distal bond of the three-membered ring in this transformation.
