Stereospecific synthesis of tetrasubstituted Z-enol silyl ethers by a three component coupling process
摘要:
The coupling of an acylsilane, 2-propenyllithium and an alkyl halide produces tetrasubstituted Z-enol silyl ether in good yields, and provides the first route to these isomerically pure compounds. (C) 1997 Elsevier Science Ltd.
1-Boryl-1-silylalkylcoppers react with molecular oxygen in the presence of pyridine to afford acylsilanes efficiently. The one-pot process consists of two reactions: alkylation of 1-boryl-1-chloro-silylmethyllithium with Grignard reagents in the presence of copper(l) cyanide and aerobic oxidation of the alkylcopper species. This procedure enables us to access the divergent synthesis of acylsilanes.

The regio- and stereoselective preparation of fully substituted and stereodefined silylenolethers of ketones and aldehydes through an allyl-Brook rearrangement is reported. This fast and efficient method proceeds from a mixture of E and Z isomers of easily accessible starting materials.
