A bidirectional synthesis of spiroacetals via Rh(ii)-catalysed C–H insertion

Author affiliations

Abstract

Acyclic methylene acetals bearing two diazoester subunits have been converted to [5,5]-spiroacetals VIA bidirectional C–H insertion under Rh(II) catalysis. Using a chiral Rh(II) catalyst, the major diastereomer can be produced in high enantiomeric excess (89%).
