Total synthesis of cryptomoscatone F1 through an asymmetric aldol approach
摘要:
A stereoselective total synthesis of naturally occurring styryl lactone, cryptomoscatone F1 is described. A Mukaiyama asymmetric aldol reaction, Brown's asymmetric allylation, Maruoka asymmetric allylation, and cross metathesis were used as the key steps. (C) 2015 Elsevier Ltd. All rights reserved.

The stereoselective total synthesis of passifloricin A (1), a naturally occurring dihydropyranone with leishmanicidal and antiprotozoal activities, has been accomplished starting from protected glyceraldehyde using Maruoka asymmetric allylation, diastereoselective iodo‐carbonate cyclization, and Grubbs' olefin metathesis reactions as the key steps.

In the course of our search for new anticancer agents, a series of novel malyngamide derivatives were synthesized by sharpless asymmetric epoxidation, followed by Julia-Kocinski olefination reactions as key reaction sequence. Anticancer activities of all these derivatives were screened against IMR-32, SF-295, SKNSH, HeLa, Colon-502713, SW-620, and Hop-62 cell lines for the first time.
AbstractA simple and efficient stereoselective linear approach to the total synthesis of (−)‐pinidinone has been accomplished starting from propane‐1,3‐diol, and employing Maruoka asymmetric allylation and Grubbs' olefin cross‐metathesis as the key steps.
