Total synthesis of scytophycin C. 2. Coupling reaction of the C(1)-C(18) segment and the C(19)-C(31) segment, a key macrolactonization, and the crucial terminal amidation reaction

[Equation presented] Stereoselective syntheses of the C(1)-C(18) segment (segment A) and the C(19)-C(31) segment (segment B) are described in the preceding paper. This paper reports the key coupling reaction of both segments, 22-membered lactonization, an
