Direct intramolecular aminoboration of sulfonamidoallenes was realized using BCl3 as a boron source. The reactions benefited from the interaction between BCl3 and sulfonamides and provided a variety of borylvinyl heterocycles in good isolated yields. When chiral substrates were involved in the reactions, high stereoselectivity was observed, as can be ascertained by single-crystal X-ray diffraction experiments. Derivatization of the thus-obtained borylvinyl compounds proceeded readily, and different functionalities could be obtained via oxidation, halogenation, and Suzuki coupling reactions.

Synthetic studies on the solanacol ABC ring system by cation-initiated cascade cyclization: Implications for strigolactone biosynthesis

supporting information; experimental part, p. 5350 - 5353 (2011/09/13)
We report a new method for constructing the ABC ring system of strigolactones, in a single step from a simple linear precursor by acid-catalyzed double cyclization. The reaction proceeds with a high degree of stereochemical control, which can be qualitatively rationalized using DFT calculations. Our concise synthetic approach offers a new model for thinking about the (as yet) unknown chemistry that is employed in the biosynthetic pathways leading to this class of plant hormones.

Tandem Henry/oxa-Michael route to the 1,3-disubstituted-1,3-dihydrobenzo[c] furan system
Luzzio, Frederick A.,Okoromoba, Otome E.
scheme or table, p. 6530 - 6533 (2012/01/02)
The reaction of ortho-formyl cinnamates and ortho-formyl-α- benzalketones with suitably substituted alkylnitro compounds in the presence of 1,1,3,3-tetramethylguanidine results in the formation of 1,3-disubstituted dihydroisobenzofurans. The reaction mechanism entails a base-mediated nitronate addition to the aryl formyl group followed by intramolecular alcoholate addition to the unsaturated component that then affords the isobenzofuran system.
