Solid-phase synthesis of hydroxy-acids leading to macrolactones
摘要:
A sequence of five chemical steps on solid support yields hydroxy-acids in a very straightforward and efficient manner. The resulting compounds can be cyclized in solution phase by forming an ester bond to produce macrolactones. (C) 2000 Published by Elsevier Science Ltd.

Heterophanes are widely found in natural products and drug molecules. Herein, an efficient method for the construction of [2,5]-furanophanes with differentring types and ringsizes was developed. This method is carried out with furan-free precursor throughintramolecular carbene-mediated alkynyl migration and tandem cyclization strategy. In addition, a series of tetrafuran structures can be obtained by oxidative
