Technical Notes:

1.Starting material used for the preparation of an enantioselective catalyst in a tandem alkylation strategy for rapid terpene construction

2.Starting material for the preparation of an enantioselective catalyst used in a highly efficient, and enantioselective,

1,4- diboration of 1 ,3 dienes.

3.Starting material for the preparation of an enantioselective catalyst used in cascades of terminal alkene diboration/

cross coupling.
