  Indolocarbazoles. 4. Synthetic studies towards staurosporine and tjipanazoles: Reactions of indolocarbazole with glycals

  摘要：

  In an attempt to construct the unique N,N'-bidentate glycosyl linkage found in the Staurosporine 1 class of natural products, the first example of an acid catalyzed 2,6-condensation of an activated pyran with indolocarbazole 4 is reported. In pursuit of the real system, a variety of glycals were reacted with indolocarbazole 4. Formation of novel unexpected products (B/C) with 13-connections along with the expected product (A) and its' synthetic transformation to a potentially useful intermediate 24 are detailed.

• Enzymatic resolution of racemic glycals: an application of the wong acylation method

  日期：1991.9

  Kinetic resolution of racemic, fully synthetic, artificial glycals bearing a free hydroxyl group at C3 was accomplished through the more rapid acylation of the ''D''-antipode with vinyl acetate as acyl donor and Lipase PS-30 from Pseudomonas cepacia as catalyst.
