Controllable single- or double-oxa-Michael addition of ynones with alcohols: Synthesis of 3-alkoxyprop-2-en-1-ones and 3,3-dialkoxypropan-1-ones
摘要:
Single- or double-oxa-Michael addition of ynones with various alcohols was achieved at room temperature. (E)-3-Alkoxyprop-2-en-1-ones and 3,3-dialkoxypropan-1-ones were efficiently synthesized by time-controlling approach. This protocol has advantages of wide range of substrates, no transition metal catalyst, mild condition, high yield and high stereoselectivity. (C) 2018 Elsevier Ltd. All rights reserved.

The alpha-haloenones undergo cine-substitution upon reaction with phenolic reagents under basic conditions. A convenient method for the synthesis of push-pull aroxyenones was developed based on this reaction. (C) 2015 Elsevier Ltd. All rights reserved.
