Palladium-catalysed cyclisation and functionalisation of 1,1-diacetoxy-2,7-diene and 1,1-diacetoxy-2-en-7-yne derivatives
摘要:
The palladium-catalysed 'metallo-ene' cyclisation, cyclisation/carbonylation, -vinylstannane coupling, and Pd(II)-catalysed chloropalladation/carbocyclisation of 1,1-diacetoxy-2,7-diene and 1,1-diacetoxy-2-en-7-yne derivatives are described. The cyclic enolacetate products could readily be converted into the corresponding aldehydes that are amenable to further transformation. (C) 1998 Elsevier Science Ltd. All rights reserved.
