A novel route to 2-fluoromethyl- and 2-hydroxymethyl-4-alkyl furans via allene oxides
摘要:
A four-step protocol for the synthesis of 2-fluoromethyl and 2-hydroxymethyl 4-alkyl furans 1a and 1b from a-alkyl acroleins 4 and 1-bromo-1-trimethylsilylethylene (5) via allene oxides 2 is elaborated, and is applied to the preparation of steroid furans 10, 11, 14 and 15 from alpha,beta-unsaturated aldehyde 8.
