An enantioselective method to prepare trans-fused bicyclo[5.3.0]decane systems is described. This methodology is based on two key reactions: a [4+3] cycloaddition reaction (to generate the seven-membered ring) and the Nicholas reaction (to insert the five-membered ring). The application of this methodology to the enantioselectivesynthesis of the pseudoguaiane carbon skeleton is presented. This enantioselective

0]decane systems is presented. It is a very versatile methodology based on two key reactions: [4+3] cycloaddition reaction (to generate the seven-membered ring) and the Nicholas reaction (that facilitates the insertion of the five-membered ring). This methodology allows the easy preparation of a wide range of bioactive natural products containing the trans-fused bicyclo[5.3.0]decane system. The application
