Letter - R.Michael Mondavi to Donald Ziraldo, 1997

A letter from R. Michael Mondavi of Robert Mondavi Winery congratulating Donald Ziraldo on the release of his book Anatomy of a Winery and thanking him for the copy he was sent. He comments on the beautiful images and compares the beauty of the photographs with the landscape of Napa Valley. 2 May, 1997

Photograph - Donald Ziraldo, Michael Budman, Ross Rebagliati & others in Aspen, CO

A photograph of five people, some are identifiable, such as Donald Ziraldo, Roots Co-founder Michael Budman and Ross Rebagliati, Canadian professional snowboarder and Olympic gold medal winner for Men's Snowboarding at the 1998 Winter Olympics. On the back it is noted that this is Aspen Colorado in 1998. This may relate to the 1998 Winter Games as two people in the picture are wearing the Roots hat designed for that event.

Diastereoselective Synthesis of Planar Chiral N-Substituted Ferrocenes Derived from Epimeric Imidazolones and their Application to Asymmetric Hydrogenation of Quinolines

This thesis describes the synthesis and use of an N-substituted ferrocene bearing a proline-derived chiral directing group and diastereoselective lithiation-electrophile quench of the pro-Sp hydrogen of the ferrocene to give planar chiral products in >95:5 dr. The auxiliary group is found to be stable to lithium bases of types RLi and R2NLi giving the same diastereoselectivity. The anti- epimer of the previously mentioned syn auxiliary induces lithiation of pro Rp rather than pro Sp hydrogen in >95:5 dr. Upon electrophile quench and elimination, the enantiomer of the syn-derived planar chiral imidazolone is obtained. Hence, this method provides a practical way to prepare planar chiral enantiomers in this series without the use of a more expensive D-proline derived starting material. The syn and anti epimers have β, γ-stereogenic centers and the origin of stereoselectivity in lithiation appears to be driven by the conformational bias exerted by the β-silyloxy moiety in each chiral auxiliary. In the thesis, this conclusion is supported using insensitivity of lithiation selectivity to the bulkiness of the base, comparison of enantiomers, deuteration experiments, nOe difference studies and computational modeling of the ground states and lithiation transition states for both substrates. The products are then converted to ligand precursors to make iridium and rhodium complexes. Among them, one of the cationic iridium complex is found to be effective in the asymmetric hydrogenation of 2-substituted quinolines with enantioselectivities up to 80% at pressures as low as 5 atm.

Letter to Henry Nelles from Michael Harris of the Perth Military Settlement (3 pages, handwritten). He is married to Mary Fanning, sister of Henry Nelles but is having marital troubles as he says he “may have to be on the lookout for another wife”. He thinks that his wife Mary may have departed for the United States, Apr. 6, 1821.
