We recently communicated that in situ prepared chiral allyltrichlorostannanes react with chiral α-methyl aldehydes to give 1,2-syn homoallylic alcohols that are key intermediates for the preparation of polyacetate and polypropionate-derived natural products. 3., , , , 4. and 5. We have described also that chiral and achiral allyltrichlorostannanes react with N-Boc-α-aminoaldehydes to give 1,2-synN-Boc-α-aminoalcohols that are key intermediates for the preparation of ...
