  Aldol reactions of ketal-protected tartrate ester enolates. Asymmetric syntheses and absolute stereochemical assignments of phospholipase A2 inhibitors cinatrin C1 and C3

  摘要：

  An efficient approach to the syntheses of cinatrins C-1 and C-3 has been developed and used to establish the absolute configurations of these natural products. The construction of each molecule has been achieved in a five-step reaction sequence (overall yield 43% for cinatrin C-1, 33% for cinatrin C-3) from the di-tert-butyl ester of (R,R)-tartaric acid. The two contiguous, quaternary chiral centers in the cinatrin skeleton are constructed via a diastereoselective, titanium-mediated aldol coupling of a tartrate-derived silylketene acetal and an achiral alpha-ketoester. This bond construction proceeds with excellent diastereoselectivity for a variety of aldehyde and alpha-ketoester substrates. (C) 1997 Elsevier Science Ltd.

  Role of the hydrophobic moiety of tumor promoters. Synthesis and activity of 2-alkylated benzolactams

  摘要：

  The size and position of a hydrophobic moiety on a benzolactam skeleton, which reproduces the active conformation and biological activity of teleocidins, play an important role in the appearance of the activity. Compounds with alkyl groups of various sizes and shapes at the 2-position of benzolactam were synthesized. Structure-activity results indicate that a hydrophobic substituent at the C-2 position plays a critical role in the appearance of biological activities, as in the case of substitution at C-9.
