An unexpected product from attempted reductive etherification of a silyl alcohol with an aldehyde
摘要:
Reductive etherification, using BiBr3/Et3SiH, between two modified amino acids, one with a silyl alcohol side chain and one with an aldehyde side chain, gave, not the desired bis-amino acid, but a tetrahydrooxazine, in good yield. (c) 2007 Elsevier Ltd. All rights reserved.
