The asymmetric synthesis of the marine sponge natural products R-strongylodiols A R-1 and B R-2, using a minimum protection strategy, is described. Two approaches were examined and the Noyori asymmetric reduction of ynones was found to be successful for installing the chirality of the natural products. Analogue R-32 was also prepared. In addition, asymmetric alkynylation of aldehydes is briefly reviewed
描述了使用最小保护策略不对称合成海洋海绵天然产物R-强丙二醇A R - 1和B R - 2的方法。研究了两种方法,发现Noyori炔酮的不对称还原成功地确保了天然产物的手性。还制备了类似物R - 32。另外,简要回顾了醛的不对称炔基化。
