Latest Patents

Tsukamoto's latest patents include innovative processes for the synthesis of dimer alkaloid compounds. One of his patents details the "Process of synthesis of 3′,4′-anhydrovinblastine, vinblastine and vincristine." This invention outlines a multi-step process that begins with the 1,4-reduction of a first dimeric iminium intermediate to an enamine compound. The process continues with oxidative transformation of the enamine to a second iminium intermediate under controlled aeration, followed by the reduction of this intermediate to form the target dimer alkaloid compounds. Notably, the entire process can be conducted in a one-pot operation, allowing for the target compounds to be obtained without the need for isolation of intermediates.

Another patent by Tsukamoto is the "Process of synthesis of vinblastine and vincristine," which shares similar methodologies and objectives. This work further emphasizes his expertise in synthesizing complex alkaloid structures efficiently.
