Paragraph 00329; 00336; 00337, (2019/08/15)
Provided herein are compounds of Formula (I) and pharmaceutical compositions thereof, which may be useful as MALT1 inhibitors. Also provided are for the treatment of proliferative disorders (e.g., cancer (e.g., non-Hodgkin' s lymphoma, diffuse large B-cell lymphoma, MALT lymphoma), benign neoplasm, a disease associated with angiogenesis,an autoimmune disease, an inflammatory disease, an autoinflammatory disease) by administering a compound of Formula (I).
Total synthesis of depsilairdin

(Figure presented) The total synthesis of depsilairdin, a host-selective phytotoxin isolated from Leptosphaeria maculans (the causal agent of blackleg disease of oilseed Brassicas), has been achieved by N-terminal extension of a suitably protected derivative of the hitherto unknown amino acid (2S,3S,4R)-3,4-dihydroxy-3-methyl-proline (Dhmp) followed by esterification with lairdinol A. The latter esterification, complicated by the sterically hindered nature of the carboxyl group, was accomplished by a novel method involving reaction of the 1-hydroxybenzotriazole (HOBt) derived active ester with the bromomagnesium alkoxide of lairdinol A. Three depsilairdin analogues were also prepared by replacing the Dhmp residue with l-proline and cis- and trans-4-hydroxy-l-proline. Phytotoxicity assays showed that the analogues were nontoxic to both blackleg-susceptible (brown mustard) and -resistant (canola) plants, suggesting that the presence of the Dhmp residue in depsilairdin is important for its host-selective toxicity toward brown mustard.
