Abstract
Chiral bicyclo[3.2.1]octanes are constructed in high yields with up to single dr and er through [3 + 2]-annulation of hydroxy-p-quinones with α-alkylnitroethylenes with a low-loading of Rawal's quinine-squaramide-catalyst under ambient conditions.

Abstract
We have developed an organocatalytic approach for the construction of a 2,3-dihydrobenzofuran scaffold through a formal [4 + 1] annulation of 2-(2-nitrovinyl)phenols and α-bromoacetophenones in the presence of DBU.
