Rhodium catalysed carbonylation of homoallylic alcohols to spiropyrans bearing quaternary centres
TETRAHEDRON（1998）
摘要
A convenient preparation of substituted spiropyrans via rhodium catalysed hydroformylation of homoallylic alcohols, followed by a condensation sequence to form hemiacetals and 2,2,3,3 -tetraalkyl-4[H] -pyrans, is described. (C) 1998 Elsevier Science Ltd. All rights reserved.
