Ball-Jones, M.P. orcid.org/0000-0001-9131-2373, Tyler, J., Mora-Radó, H. et al. (3 more authors) (2019) Exploiting hydrazones to improve the efficiency of 6π-electrocyclization reactions of 1-azatrienes. Organic Letters, 21 (17). pp. 6821-6824. ISSN 1523-7060
Abstract
The greater geometric lability of hydrazones compared to that of oxime ethers is used as a basis to overcome the reluctance of Z-oxime ether azatrienes to undergo electrocyclization toward the synthesis of borylated (heteroaromatic) pyridines and ring-fused analogues. Such hydrazones now allow access to previously inaccessible tri- and tetrasubstituted 3-borylpyridines in high yields.
