α-d-mannopyranoside through the intramolecular Diels-Alder reaction, and the tetraenedicarboxylic acid moiety is from the enzymatically prepared anti-compound. Both moieties were coupled to accomplish the total synthesis of calbistrin A and to disclose its absolute structure.
八氢萘吡喃酮部分是通过分子内的Diels-Alder反应由甲基α-d-甘露吡喃糖苷合成的,而四烯二羧酸部分则是由酶法制备的抗化合物合成的。将两个部分偶联以完成钙调蛋白A的全合成并公开其绝对结构。
